Guinea experiences a distinct tropical climate with two very different seasons that'll shape your entire trip. The dry season runs roughly from November through April, bringing scorching temperatures that can hit 40°C (104°F) or higher, particularly in the interior regions. The wet season, spanning May through October, transforms the country with heavy rainfall—September is particularly intense with nearly 380mm (15 inches) of rain. Interestingly, temperatures actually drop during the rainy months, which might seem counterintuitive but makes the wet season more comfortable in terms of heat, even if you're dodging downpours. The climate patterns here are pretty dramatic. You'll notice the transition months can be unpredictable—May marks the shift from blistering heat to monsoon conditions, while October sees things drying out again. Humidity hovers around 70% year-round, which is worth noting because even when temperatures drop during the rainy season, that moisture in the air makes everything feel a bit sticky. The coastal areas tend to get more rainfall than the interior, and the Fouta Djallon highlands have their own microclimate that's generally cooler and wetter than the lowlands.

Best Time to Visit

Beach & Relaxation
November through February offers the best beach conditions with minimal rainfall and plenty of sunshine, though you'll want to hit the water early before midday heat becomes intense.
Cultural Exploration
December through March provides comfortable conditions for visiting markets, villages, and cultural sites, with dry weather making rural travel much more manageable on often-challenging roads.
Adventure & Hiking
November and December are ideal for trekking in the Fouta Djallon highlands—trails are dry, visibility is excellent, and temperatures are more bearable than the scorching March-April period.
Budget Travel
June through September sees fewer tourists due to heavy rains, which typically means better deals on accommodation, though you'll need to weigh savings against travel difficulties during peak wet season.

What to Pack

Year-Round Essentials

High SPF sunscreen
The sun is intense year-round, even during overcast wet season days when UV rays penetrate cloud cover.
Insect repellent with DEET
Mosquitoes are active throughout the year, particularly during and after the rainy season when standing water is abundant.
Quick-dry towel
The high humidity means regular towels take forever to dry, and you'll appreciate something that actually dries between uses.
Reusable water bottle with filter
Staying hydrated is crucial in this climate, and having your own filtration system gives you flexibility with water sources.
Anti-malarial medication
Guinea is a malaria zone year-round, so prophylaxis is essential regardless of when you visit.
Lightweight daypack
You'll want something breathable for carrying essentials during daily exploration without adding to the heat burden.
Portable phone charger
Power outages are fairly common, and you'll want to keep devices charged for navigation and communication.

Footwear
Waterproof hiking sandals or shoes with good tread for muddy conditions; flip-flops for indoor use
