Climate overview

Lagos is Nigeria's largest city, spread across islands, lagoons and mainland along the Gulf of Guinea. Its climate is tropical savanna (Aw): hot and humid throughout the year, with average highs of 28–33°C and lows of 22–24°C. Humidity rarely drops below 75%, so the heat feels heavier than the numbers suggest.

Rain is what really changes through the year. Lagos receives about 1,600 mm annually, mostly in two rainy seasons: a long one from April to July, peaking in June at about 313 mm, and a shorter one in September and October. Between them comes the 'August break', a short, drier pause. From November to March, the dry season is shaped by the harmattan wind from the Sahara.

Köppen classification: Aw — tropical savanna

What makes Lagos's weather distinctive

Flooding is the most significant weather issue in Lagos. Intense rain, low elevation, high tides and drainage challenges mean that heavy downpours can quickly flood streets, slow traffic for hours and affect homes. During the rainy seasons, it is wise to allow extra travel time.

The harmattan is the other notable phenomenon. In some years, the dust haze is thick enough to reduce visibility and delay flights. It also lowers humidity slightly, which can make dry-season mornings feel fresher.

Best time to visit Lagos

November to March is the best time to visit Lagos, during the dry season, with less rain, fewer floods and more sunshine. December is lively, with festivals and events. If you travel in the rainy season, July and August's 'break' can offer some drier days.

What to pack

  • Lightweight, breathable clothing
  • A sturdy umbrella and waterproof footwear in the rainy season
  • Sunscreen and sunglasses
  • Insect repellent
  • A light scarf or mask for dusty harmattan days
