If you want to enjoy La Digue at its best, you’ll need to plan around the island’s tropical climate. Temperatures stay warm all year, but rainfall and humidity shift with the seasons.
The most comfortable time to visit La Digue is from June through September, when the weather’s drier, the air feels less humid, and the breezes make exploring more pleasant.
During these months, you’ll get the clearest skies for swimming, cycling, and sightseeing. The ocean stays calm enough for snorkeling, and the lower chance of rain means you can spend long days outdoors without many interruptions.
This balance of sunshine, warmth, and manageable humidity makes mid-year travel feel especially rewarding.
Outside of this window, La Digue still has plenty of appeal, but conditions shift. Some months bring heavier showers, while others feel hotter and more humid.
If you know how the climate changes across the year, you can match your visit with the kind of experience you want. Maybe you want quiet beaches, active adventures, or just the most reliable weather.
Overview of La Digue’s Climate
La Digue in Seychelles has a tropical climate shaped by the Indian Ocean. You’ll get warm temperatures year-round, seasonal rainfall, and steady sea conditions that make swimming possible every month.
Tropical Weather Patterns
La Digue’s climate follows a tropical rainforest classification. You’ll experience warm conditions with little variation in daylight and temperature throughout the year.
The island sits outside the main cyclone belt, so you won’t deal with extreme storms like in some other tropical places. Instead, seasonal winds called the southeast trade winds bring cooler, drier air from May to September.
From November to April, the northwest monsoon takes over. This period often brings higher humidity, heavier showers, and calmer seas.
These shifts create two main travel seasons: one with drier, breezier weather, and one with wetter, more humid conditions.
Because of its location, La Digue keeps stable sea temperatures that stay comfortable for swimming and snorkeling. That’s one big reason travelers visit all year.
Temperature Ranges Throughout the Year
Temperatures in La Digue stay steady, usually between 27°C and 30°C (81°F to 86°F). Unlike places with sharp seasonal swings, the island’s warmth is pretty much continuous.
March and April usually bring the hottest weather, with daytime highs close to 30°C. Nights stay mild and rarely drop below 24°C.
The coolest months are July and August. During this time, daytime temperatures average around 26–27°C, and evenings feel a bit fresher.
These months are great for hiking or cycling, which are super popular ways to see the island.
Since temperature changes are small, you can plan outdoor activities any time of year without worrying about extreme heat or cold. The main thing that changes is how humid it feels.
Rainfall and Humidity Trends
Rainfall in La Digue varies a lot by month. The wettest period is December through February, when monthly totals can hit 300–400 mm or more. Showers can be heavy, especially in January, but they’re often brief.
The driest stretch is from June to August, with rainfall dropping to about 100–150 mm per month. These months also get stronger southeast trade winds, which lower humidity and make the air feel cooler.
Humidity stays high all year, usually above 75%. You’ll notice the air feels heavier during the wet monsoon months, but the drier season is much more comfortable.
Even with frequent rain, sunshine hours stay steady, averaging about 7 hours per day. Rain usually comes in short bursts, so you’ll still have plenty of time for outdoor fun.

You can count on La Digue for year-round water activities.
Best Months to Visit La Digue
La Digue in Seychelles has warm, tropical weather year-round, but some months are just more comfortable for exploring and relaxing. If you plan your visit around temperature, rainfall, and wind patterns, you’ll get the most out of your trip.
Peak Weather Periods
The best stretch of weather usually comes between July and September. During these months, daily highs average around 29°C (84–85°F), and humidity is a bit lower than earlier in the year.
Rainfall is at its lowest, with only about 3–4 inches per month, so you can hit the beaches and cycling paths without dodging too many showers.
Winds are moderate but steady, averaging 11–12 knots in August. This keeps the air comfortable, even with the tropical heat. These breezes also make the island less humid compared to January or April, which can feel kind of stifling.
If you want the driest and most predictable weather, August is the standout. It has the lowest chance of rain, the coolest temperatures, and the windiest conditions, which really takes the edge off the heat.
Ideal Months for Outdoor Activities
If swimming, snorkeling, or diving is your thing, the sea conditions between November and May are often better. Water temperatures average 28°C (82°F), and the calmer seas make it easy to enjoy marine activities.
For hiking and cycling, the June to September period is best. The cooler air and less rain help you stay comfortable while exploring trails or riding around the island.
You’ll also find fewer crowds compared to the busy tourist months like January or May.
Here’s a quick comparison:
| Activity | Best Months | Conditions |
|---|---|---|
| Beach & Sunbathing | Jun–Sep | Dry, cooler, less humid |
| Swimming & Diving | Nov–May | Warm sea, calmer waters |
| Hiking & Cycling | Jul–Sep | Breezy, low rainfall |
If you time your trip right, you’ll enjoy La Digue’s beaches, trails, and waters under the best possible conditions.
Seasonal Considerations
Weather patterns in La Digue shift with the trade winds and the flow of tourists. These factors shape sea conditions, rainfall, and how crowded the island feels at different times.
Trade Winds and Their Impact
La Digue’s climate is tropical, but the southeast and northwest trade winds create seasonal differences. From May to September, the southeast trade winds take over. They bring cooler air, lower humidity, and choppier seas.
This period is generally drier, and July and August offer some of the best conditions for outdoor activities.
During the northwest trade wind season from November to March, the air feels warmer and more humid. Rain showers are more frequent, especially in December and January.
Rainfall is often short-lived, but it can affect visibility for diving and snorkeling.
Wind direction also shapes the beaches. Anse Source d’Argent is more sheltered during the southeast trade winds, while the eastern beaches like Grand Anse get stronger surf.
If you want to swim or snorkel, pick your beaches based on the season’s wind.
High and Low Tourist Seasons
Tourism in La Digue follows the weather’s rhythm. The peak season runs from July to September and again in December to January. These months combine either dry, breezy weather or holiday travel demand, so you’ll see higher accommodation prices and busier beaches.
The shoulder months—April, May, October, and November—offer a nice balance of good weather and fewer crowds. Rainfall is moderate, and sea conditions are calmer. Travelers looking for value and comfort often pick these months.
The low season usually falls in January through March, when rainfall is heavier and humidity is high. You might find lower hotel rates, but outdoor plans can get disrupted by showers and rougher seas.
Careful planning helps you make the most of these quieter months.
Comparing La Digue With Nearby Islands
La Digue and its neighboring islands share a lot of tropical traits, but small differences in rainfall, wind, and temperature can shape your experience. These little shifts matter when you’re deciding where to stay or what to do.
Weather Differences With Praslin
Praslin sits just a short ferry ride from La Digue, but the two islands don’t always feel the same. La Digue gets slightly stronger winds during the southeast trade wind season, especially in July and August.
This makes cycling and beach visits breezier compared to Praslin, which is more sheltered.
Rainfall patterns also differ. Praslin’s larger landmass and higher hills create more localized showers, while La Digue tends to have shorter bursts of rain.
On average, both islands stay warm year-round, with daytime highs around 29–31°C (84–88°F). Praslin can feel more humid in sheltered areas.
If you’re planning outdoor activities, Praslin’s forests and Vallée de Mai might feel more humid, while La Digue’s open beaches like Anse Source d’Argent feel cooler in the wind.
Both islands offer swimmable seas most of the year, but La Digue’s waters can be a bit rougher during windy months.
Regional Climate Variations
Across the Seychelles, the islands share a tropical climate with little temperature change, but rainfall and wind can vary by location.
The inner islands, including La Digue and Praslin, get more rain than the outer coral atolls, especially from December to February.
La Digue sits east of Praslin, so it catches the wind earlier during the southeast monsoon. This sometimes makes it feel less humid, even though the actual temperatures are pretty much the same.
Praslin’s inland valleys can trap moisture and make things feel warmer and stiller.
So when you compare the two, it really comes down to exposure to wind, rainfall intensity, and humidity levels. These small differences can affect how comfortable you feel while hiking, cycling, or spending long hours at the beach.
Travel Tips for Weather-Ready Visits
La Digue in Seychelles has a warm, tropical climate with only small seasonal changes. If you prepare for heat, humidity, and the odd rain shower, you’ll stay comfortable and really make the most of your trip.
Packing Advice for Each Season
Pack light, breathable clothing all year, since daytime highs usually hover between 29°C and 32°C (84°F–90°F). Cotton or linen just feels better in the humid air.
From June to August, winds pick up a bit. Toss a light jacket or windbreaker in your bag if you’re planning to cycle or take a boat ride.
A compact raincoat or poncho comes in handy, especially from December to April when rain shows up more often.
Footwear really matters on La Digue. Bring sandals or flip-flops for the beach, but you’ll want sturdy walking shoes if you’re thinking about hitting forest trails or those granite paths.
Don’t forget sun protection, no matter when you visit. Pack reef-safe sunscreen, sunglasses, and a wide-brimmed hat. A reusable water bottle helps you stay hydrated in the heat.
If you’re coming during the wetter months, a dry bag keeps your electronics and valuables safe during boat rides or those sudden downpours.
Weather-Related Activity Planning
La Digue’s weather really shapes when you’ll have the most fun with certain activities. From June to September, you’ll find drier, breezier days that make cycling around the island or hiking to Anse Cocos and Nid d’Aigle a lot more comfortable. The winds usually pick up, so sailing and windsurfing become pretty tempting then.
If you visit between April and May or October and November, the seas calm down and set the stage for snorkeling and diving. The water gets clearer, and you’ll probably spot more marine life than usual.
Wetter months like December and January don’t rule out beach days, but you’ll need to plan for a few quick rain showers. Maybe duck into a local craft shop or try a cooking class if the skies open up.
Want fewer crowds? The June to August period brings quieter beaches since fewer tourists show up, even if it’s a bit breezier. Always check the local forecast before heading out, because tropical showers can surprise you.
