Alabama’s weather follows familiar seasonal cycles, which makes planning trips a bit easier if you know what to expect each month. The state sits in a humid subtropical climate, so you’ll notice big differences between those sticky, hot summers and the milder, wetter winters.
Temperatures swing from winter lows in the 30s to summer highs close to 90°F. Most folks find spring and fall the most comfortable.
Weather patterns shift noticeably between the northern and southern parts of Alabama. Up north in places like Birmingham and Huntsville, you’ll get slightly cooler temps and sometimes even a bit of winter weather. Meanwhile, Mobile and the coast stay warmer almost all year.
These differences really matter when you’re picking the best time to visit different areas. They can make or break a trip, honestly.
If you keep an eye on Alabama’s monthly precipitation, temperature swings, and humidity, you’ll be better prepared for anything from summer storms to the rare winter snow. Every month brings its own quirks that shape how people plan outdoor activities, travel, and even daily routines in the Heart of Dixie.
Overview of Monthly Weather in Alabama
Alabama’s climate sticks to a pattern of hot, humid summers and pretty mild winters. The humid subtropical climate means rainfall shows up year-round, though some months definitely get more than others.

Precipitation Patterns and Rainfall
Alabama gets between 52 and 62 inches of rain per year, with the coast getting the most. Rainfall patterns and timing really depend on where you are in the state.
Wettest and Driest Months
Central and Northern Alabama get their most rain from November to April. December and March are usually the wettest.
August to October are the driest months up north. Winter storms bring more rain during the wet season.
Southern Alabama and the coast follow a different rhythm. July and August see the most rain from frequent thunderstorms.
Mobile is the rainiest city in Alabama. It stays wet almost all year, except October, which is a little drier.
Coastal winters are still pretty wet. Up north, summers are usually drier.
Regional Variation in Rainfall
The Gulf Coast averages around 62 inches of rain a year. Mobile and nearby spots get the most.
Interior regions see about 52 inches. That 10-inch gap comes from the Gulf’s influence.
The closer you are to the Gulf, the more rain you’ll get. Warm water brings in extra moisture.
Mountain areas in northeast Alabama can see different rain patterns. Elevation changes how storms form and move.
Statewide, the average is about 56 inches. Most places are pretty close to that number.
Typical Storm Events
Thunderstorms account for most of Alabama’s rain. They’re common in summer, but spring storms tend to be nastier.
Warm months bring regular storms, often dropping heavy rain in a short time.
Hurricanes and tropical storms hit the south from July to October. These can dump inches of rain as they move inland.
Even far from the coast, you’ll feel the effects of tropical systems. The storms weaken but still soak the state as they head north.
Winter storms bring the wet season to the north and central areas. These are usually steady, soaking rains, not quick downpours.
Snow barely adds to the yearly total. North of Montgomery, most spots only get light dustings a few times each winter.
Best Time to Visit Alabama for Weather
Spring and fall are the best bets for comfortable weather in Alabama, with mild temps and lower humidity. Summer is the busiest for tourists but can be brutally hot, while winter is less crowded and cheaper if you don’t mind cooler air.
Ideal Months for Outdoor Activities
March through May is prime time for getting outside in Alabama. Temps run from 60°F to 75°F, perfect for hiking, camping, or just exploring.
April, in particular, is a favorite for outdoor fans. Humidity hasn’t cranked up yet, so it still feels nice.
September through November is another great stretch for outdoor stuff. Fall temperatures make fishing, golf, and photography a lot more pleasant.
October often brings what many call perfect weather. Temps stay between 60°F and 75°F with little rain.
From December through February, outdoor activities get trickier. Up north, temps can dip below freezing, but the coast stays milder.
Summer heat from June to August can hit 95°F with high humidity. If you’re braving the summer, stick to early mornings or evenings.
Seasonal Tourism Peaks
Summer draws the most visitors, especially to the Gulf Coast. June through August is peak tourism, even though it’s often 85°F to 95°F.
Beach towns are packed in summer. Families flock to the coast for water fun.
Spring tourism picks up from March to May. The weather is nice, and crowds aren’t as bad as summer.
Fall tourism is steady but not overwhelming. September through November offers good weather and fewer people.
Winter is the slowest season for tourism. December through February brings out the budget travelers who don’t mind some chill.
February is the best time for deals. Hotels and attractions often offer big discounts during these slower weeks.
Climate Considerations for Travelers
Humidity levels really shape how comfortable you’ll feel while visiting Alabama. Spring and fall usually bring lower humidity, which feels a lot nicer than summer’s thick, sticky air.
In the summer, humidity ramps up and can make 85°F feel way hotter than you’d expect. If you’re visiting then, you’ll probably want to plan some indoor escapes during those sweaty afternoon hours.
Precipitation patterns change a lot depending on the season. Spring might surprise you with a thunderstorm or two, but summer? Afternoon showers happen all the time.
Every so often, winter brings a dusting of snow up in northern Alabama. Down south, frozen precipitation is almost unheard of.
Temperature variations pop up all over Alabama. The northern mountains usually stay cooler, while the southern coastal plains get warmer.
Coastal areas, thanks to the Gulf, keep things a bit more moderate year-round. Winters feel warmer there, and summers don’t get quite as sweltering as they do inland.
No matter when you visit, packing layers is a smart move. Temperatures can swing more than 20°F between day and night, and you don’t want to get caught off guard.
Additional Weather Factors in Alabama
Alabama’s climate throws some interesting curveballs beyond just temperature and rain. High humidity makes summer heat feel downright brutal, and the state’s daylight hours shift a lot through the year. Oh, and let’s not forget—Alabama sits in one of the country’s busiest tornado zones.
Humidity and Heat Index
High humidity turns Alabama summers into a real sauna, way worse than the thermometer lets on. The Gulf of Mexico keeps pumping moisture into the air, so it’s almost always muggy.
In July and August, humidity often climbs to 80-90%. When it’s 90°F, the heat index can easily hit 105°F or more.
That combo creates some pretty risky conditions for anyone spending time outside. Once the heat index passes 100°F, heat exhaustion and heat stroke become real concerns.
Spring and fall feel a lot more comfortable, with humidity hovering around 60-70%. Winters are the driest, usually staying between 50-65%.
People living here and visitors alike should keep an eye on heat index warnings during summer. That sticky air makes it tough for the body to cool off by sweating.
Sunshine and Daylight Hours
Alabama gets plenty of sunshine most of the year. Summer months can bring up to 14 or 15 hours of daylight, with sunrise as early as 5:30 AM and sunset close to 8:00 PM.
Winter daylight drops to just about 9 or 10 hours. December days feel shortest, with sunrise around 6:45 AM and sunset already by 5:00 PM.
On average, the state enjoys 220-240 sunny days each year. July usually shines the brightest, while December and January tend to be the gloomiest.
Cloud cover thickens during winter when weather systems roll through more often. Spring and fall? Those seasons usually serve up clear skies and just-right daylight.
All this sunshine shapes what people do outside, impacts local farming, and even bumps up energy bills in the summer. Longer days mean more time for fun, but also higher cooling costs.
Tornado and Severe Weather Season
Alabama actually sits in the southeastern extension of Tornado Alley, and locals see the most tornado activity from March through May.
Each year, tornadoes hit the state about 30 to 50 times.
April is usually the most dangerous month for severe weather. When warm, humid air from the Gulf collides with cooler, drier air from the north, it sets up those classic tornado conditions.
Severe thunderstorms often pop up fast in the late afternoon or evening. These storms can bring damaging winds, big hail, and plenty of dangerous lightning.
The Tennessee Valley region really gets the brunt of tornadoes. Folks in northern Alabama counties see more frequent and intense tornadoes than those farther south.
Hurricane season stretches from June through November and tends to affect coastal Alabama the most. These storms dump heavy rain, cause flooding, and sometimes even spin up tornadoes inland.
People rely on weather alerts and warning systems to get ready for rough conditions. Most tornadoes strike between 3:00 PM and 9:00 PM, right when the atmosphere feels most unstable.
