If you’re planning a trip to Louisiana, you’ll want to get a handle on the state’s unpredictable climate. The weather here can swing from dreamy to downright difficult, and it’ll absolutely shape your travel experience.
Honestly, the best time to visit Louisiana for weather is February through May. Temperatures stay comfortable, rain backs off quite a bit, and hurricane risks are pretty low. During these months, you’ll see daytime highs from the mid-60s in February to the mid-80s in May, which is just about perfect for city strolls or outdoor adventures.
Knowing Louisiana’s weather patterns can help you dodge the worst of the summer heat, avoid those relentless downpours, and steer clear of hurricane season. This guide breaks down seasonal weather, regional quirks, and timing tips so you can pick the best window for your plans—whether you’re chasing festivals or just want to relax.
Weather Patterns in Louisiana: What to Expect
Louisiana sits in a humid subtropical climate zone, so you’ll get hot summers, mild winters, and a good bit of moisture year-round.
The state cycles through wet and dry spells, and hurricane threats ramp up from June through November.
Overview of Louisiana’s Climate
Louisiana’s spot on the Gulf of Mexico really shapes its weather. Warm, damp air sweeps in for most of the year, keeping things lush—and sometimes sticky.
You’ll notice two main seasons: a wet one from June to October, and a drier stretch from November to May. Summers get steamy, with heat and humidity teaming up to make things uncomfortable fast.
A few climate quirks:
- Humidity sticks around all year
- Afternoon thunderstorms pop up a lot in summer
- Winters rarely get harsh
- Hurricanes threaten most from late summer into fall
New Orleans and Baton Rouge share similar patterns. The Gulf keeps winter temps surprisingly mild.
Snow’s a rarity here. Even in January, it barely ever gets cold enough to freeze for long.
Average Temperatures by Season
Winter (December-February) brings the coolest days. In New Orleans and Baton Rouge, highs hover around 62-65°F.
Nights dip into the 40s, and January usually claims the title for coldest month.
Spring (March-May) warms things up nicely. March sees highs around 70°F, and by May, you’re looking at 85°F.
This season feels the best for outdoor fun. Humidity hasn’t spiked yet, so it’s still pleasant.
Summer (June-August) turns up the heat. Highs hit the low 90s almost everywhere.
July’s the scorcher, often topping 91°F. Thanks to all that moisture, it feels even hotter—sometimes over 100°F.
Fall (September-November) cools things off gradually. September’s still toasty, but by November, highs settle in the 70s.
October is the true transition, with highs in the low 80s.
Rain, Humidity, and Sunlight Trends
Louisiana gets about 60 inches of rain each year. The wet season, from June through October, dumps the most, with heavy downpours and storms.
Here’s how the rain usually plays out:
- Driest months: February-April (7-8 rainy days)
- Wettest months: June-September (12-15 rainy days)
- Peak hurricane season: August-October
Humidity? It barely ever drops below 60%. Summers can feel brutal, with 80-90% humidity.
Hurricane season runs from June 1 to November 30. Louisiana faces real storm risks during these months, especially in August and September.
Sunshine is generous, with 2,600-2,700 hours a year. Days stretch longest in summer, while winter days are shorter but still mild.
Afternoon thunderstorms? They’re part of summer life. Expect quick, heavy rain and sometimes some wild weather.
Best Time to Visit Louisiana Based on Weather
Louisiana’s climate has some real mood swings, and they matter for your trip. You’ll find two main stretches with comfortable temperatures and tolerable humidity. The other seasons have their own charm, but you’ll face more weather headaches.
Late Winter to Spring: The Sweet Spot
February through May is when Louisiana really shines. Highs hover in the 60s to low 80s Fahrenheit.
Spring here hits the sweet spot—warm but not sweaty. March averages 71°F, and by May you’re at a lovely 83°F. Humidity stays under control.
Rain barely shows up. March, April, and May only see a 7-8% daily chance of rain. That means outdoor plans are usually safe.
The February 19th to May 6th stretch is prime, based on the numbers. Nights cool off into the 50s and 60s, which feels great after a sunny day.
Spring’s weather is perfect for wandering bayous, plantations, and old neighborhoods. Festivals and walking tours are way more fun without the summer’s punishing heat.
Shoulder Seasons: Autumn Highlights
October through December brings another good weather window. Fall offers a break from summer’s intensity, with highs dropping from the 80s in September to the 60s by December.
October is a real winner. Highs average 80°F, and humidity drops to 63%—the lowest all year. Rain chances shrink to just 5% each day.
Fall is mostly dry, so outdoor activities are a safe bet. September through November rarely get soaked, and November is as dry as March.
December through February keeps things comfortable. Winter highs stick in the 60s. Snow might show up, but it almost never sticks around.
The October 8th to December 30th timeframe is great for cultural tours and bayou trips. Cooler days make exploring so much easier than sweating through summer.
Trade-offs of Visiting in Summer
June through August is when Louisiana tests your tolerance. Highs hit the upper 80s to low 90s, and August usually peaks at 91°F.
Humidity makes the air feel even thicker. The “feels-like” temp often overshoots the actual number.
Rain picks up in summer. July’s the wettest, with a 10% daily chance and lots of afternoon storms.
Still, summer has its perks. Tourist spots stay open late, and there’s plenty to do on the water.
Air conditioning saves the day in hotels and restaurants. Most visitors plan indoor activities for the hottest part of the afternoon.
Winter Visits and Off-Peak Advantages
December through February is the mildest season. Highs sit in the low to mid-60s, so heavy coats aren’t needed.
Sometimes it snows, especially in January. The average snow depth is 2.6 inches, but it really depends on the year and where you are.
January and February are the quietest months. Fewer tourists mean better deals on hotels and shorter lines everywhere.
Winds pick up a bit in winter, averaging 8.5 knots in January. That breeze can make it feel chillier than the numbers suggest.
Mild temps mean you can still do most outdoor stuff. Plantation tours, historic walks, and bayou trips are all on the table.

Louisiana’s Festivals and Events by Season
Louisiana’s festival calendar never really stops. Mardi Gras dominates winter and spring, music festivals heat up in the warmer months, and fall brings a steady stream of cultural events. Each season has its own vibe, and there’s always something happening to showcase the state’s wild musical and cultural spirit.
Mardi Gras: Parades and Parties
Mardi Gras turns Louisiana into a wild, colorful celebration from mid-February through early March. In New Orleans, the party lasts two weeks, with parades, floats decked out in glitter, and costumed riders tossing beads to the screaming crowds.
Baton Rouge throws its own family-friendly Mardi Gras parades. In smaller Acadian towns like Church Point, you’ll find more traditional festivities—think costumed runs and even chicken-chasing competitions.
The festival date shifts every year because of the Catholic calendar, but it always lands on the Tuesday before Ash Wednesday. The weather stays pretty mild, usually hovering around 65°F in February.
If you want to visit, you really need to book your hotel months ahead. Prices shoot up fast during this peak season.
Spring and Early Summer Events
Spring in Louisiana means music festivals everywhere. The New Orleans Jazz & Heritage Festival kicks off in late April and early May, bringing local and international artists to multiple stages.
In April, the French Quarter Festival takes over the historic French Quarter with free performances. This event spotlights Louisiana music—jazz, blues, Cajun, you name it.
The Baton Rouge Blues Festival happens in April, pulling in blues musicians from all over the region. March brings the Tennessee Williams & New Orleans Literary Festival, blending literature and live performances.
During spring festivals, the weather feels perfect for being outside. Temperatures usually sit in the mid-70s to low 80s, and there’s less rain than in summer.
Fall Festivals and Cultural Highlights
In October, the Voodoo Music + Arts Experience brings rock, electronic, and alternative acts to New Orleans’ City Park. The festival draws a younger crowd and lasts several days.
Fall is also peak food festival season. Beignet Fest and the Oak Street Po-Boy Festival celebrate Louisiana’s food in November, just as the tourist crowds start to thin.
October means the Crescent City BBQ & Blues Festival fills the air with music and the smell of barbecue. September marks the start of LSU football season in Baton Rouge, and tailgate parties make the city buzz.
Fall weather finally cools things off, but rain gets more frequent. Hurricane season still runs through November, so you’ll want to keep your travel plans flexible.
Winter Celebrations and Lights
December brings holiday lights and celebrations to cities all over Louisiana. New Orleans lights up the French Quarter and offers special holiday tours of historic homes.
Baton Rouge puts on winter festivals and holiday markets. January’s Allstate Sugar Bowl brings college football fans to New Orleans, along with plenty of parties.
January and February feel a bit quieter before Mardi Gras kicks in. Museums and historic sites stay open with fewer crowds, so winter is a great time for indoor exploring.
Winter temperatures usually range from the 40s at night to the 60s during the day. Most days, a light jacket is all you need for outdoor activities.
Regional Weather Variations and Destinations
Louisiana’s weather changes a lot depending on where you go. Down in New Orleans, it’s humid and coastal. Around Baton Rouge, things get a bit drier. Head north, and you’ll find forested areas with their own climate quirks. Every region has its own best time to visit.
New Orleans: Weather and Events
New Orleans sits right by the Gulf of Mexico and below sea level, so it’s easily the most humid spot in Louisiana. In summer, temperatures regularly hit 91°F, and the humidity can feel brutal.
The French Quarter really isn’t much fun for walking tours or outdoor dining from June through August. It just feels sticky and hot.
Best times to visit New Orleans:
- February-March: Mardi Gras, around 65°F
- April-May: French Quarter is perfect for exploring (70-85°F)
- November: Nice weather returns after hurricane season
From June to October, rain pours down the most, with September averaging 15 rainy days. Outdoor plans get tricky during these months.
In winter, daytime highs hover in the 60s. Hotels often lower their rates in December and January, unless there’s a big event happening.
Baton Rouge: Climate Patterns and Local Tips
Baton Rouge sits about 80 miles inland from New Orleans, so you’ll notice the weather shifts a bit. It’s less humid and just a little cooler than the coast.
Temperature differences from New Orleans:
- Summer: 2-3°F cooler
- Winter: Pretty much the same
- Humidity: 5-10% lower all year
Being inland gives Baton Rouge some protection from coastal storms, but hurricanes can still bring heavy rain and flooding.
LSU football season runs September through November. Tailgating gets more comfortable as temps drop from the 80s into the 70s.
Spring warms up quickly from February to May. March, especially, feels great for being outdoors, with highs in the low 70s.
Baton Rouge gets a dry spell from December to March, with rain showing up only 6-8 days each month.
Natural Wonders: Kisatchie National Forest & Atchafalaya Basin
Kisatchie National Forest up north stays cooler than the southern parts of the state. Winter lows can dip into the mid-30s, while summer highs rarely get past the upper 80s.
The forest offers the most comfortable summers in Louisiana. Hiking trails stay open even when the south gets too hot and muggy.
Best times for Kisatchie:
- Fall: October-November, with colorful leaves and 60-75°F temps
- Spring: March-April, wildflowers and mild weather
- Winter: December-February, crisp hiking conditions
Atchafalaya Basin is Louisiana’s biggest wetland. Summers here bring extreme humidity and frequent flooding.
Water levels swing a lot between seasons. Spring works best for swamp tours and wildlife spotting.
The basin almost shuts down during peak hurricane season. September and October bring the highest risks for storms and flooding.
Morning tours work best in summer. By 10 AM, the heat ramps up and afternoons get tough to handle.
Important Weather Considerations for Travelers
Louisiana’s subtropical climate means humidity, storms, and hurricanes can all mess with your plans. Travelers really need to be ready for wild weather and should know a bit about the state’s history with big storms.
Hurricane Season and Safety Tips
Hurricane season runs from June 1 through November 30, with most action between August and October. Louisiana faces a higher hurricane risk than most other coastal states because it sits on the Gulf of Mexico.
Travelers should keep an eye on weather forecasts during these months. The National Hurricane Center sends out updates and evacuation orders if storms get close.
Essential Safety Preparations:
- Download weather apps with emergency alerts
- Store important documents in waterproof containers
- Find out evacuation routes from your hotel or rental
- Keep emergency contacts handy
Businesses and attractions often close during hurricane warnings. Hotels sometimes put strict cancellation policies in place when storms threaten.
Travel insurance that covers weather-related cancellations can save you a lot of hassle. Flight delays and cancellations get pretty common when storms approach.
Packing Essentials by Season
Summer (June-August):
- Lightweight, breathable clothes
- Rain gear and waterproof shoes
- High SPF sunscreen
- Insect repellent with DEET
Fall/Spring (September-November, March-May):
- Layered clothes for changing temps
- Light jacket for evenings
- Good walking shoes
- Small umbrella
Winter (December-February):
- Warm layers for 40-60°F days
- Waterproof jacket
- Long pants and closed-toe shoes
- Light sweater or fleece
Humidity sticks around all year, so cotton and moisture-wicking fabrics really help. Rain can show up anytime, so waterproof gear is a must.
Air conditioning blasts inside most places in summer. Bring light layers so you can adjust when you go from the heat outside to the chilly indoors.
Historical Weather Events: Hurricane Katrina’s Impact
Hurricane Katrina hit Louisiana in August 2005. It stands as the most devastating natural disaster in the state’s history.
The Category 3 storm caused catastrophic flooding when the levees broke in New Orleans. Water rushed in, and the city just couldn’t hold it back.
After Katrina, Louisiana completely overhauled its emergency preparedness systems. Officials set up better evacuation plans and made building codes stricter in flood-prone neighborhoods.
Many tourist spots rebuilt with stronger flood protection afterward. Places like the French Quarter and Garden District, sitting on higher ground, didn’t get hit as hard.
Current Storm Protections:
- New Orleans now has beefed-up levee systems
- Early warning systems got a big upgrade
- Emergency agencies work together more closely
- Coastal areas follow tougher building rules
Katrina really drove home how important flood insurance and evacuation planning are. Visitors now get the benefit of these safety improvements and faster emergency response.
Weather tracking tech today offers earlier, more accurate storm predictions than what people had during Katrina. Travelers can adjust their plans with a bit more peace of mind when bad weather heads their way.
