Best Time to Visit Lamu, Kenya

January & February; Hot, Dry and Sunny

January and February mark Lamu’s short dry season, with hot days, brilliant sunshine and warm, calm seas. These are two of the best months to visit if you want uninterrupted beach weather. The water visibility is excellent — ideal for snorkelling, diving and dhow sailing — while deep-sea fishing thrives as billfish such as marlin and sailfish patrol offshore waters.

During this time, the Kaskazi winds (north-easterly trade winds) blow gently across the coast. These are typically light to moderate, creating just enough breeze to cool the afternoons without disturbing the sea. It’s also a popular period for international travellers escaping the European winter, giving the island a lively yet relaxed atmosphere.

March; Transition to the Long Rains

March begins warm and sunny, though by mid-month humidity rises and short showers become more frequent. The Kaskazi winds begin to fade and the weather turns more variable, with calmer, heavier air and the first hints of the long rainy season ahead. Fishing remains good, and the sea is still relatively clear early in the month, but visibility can begin to decline as rainfall increases.

This is a good month for balance — fair weather, lighter crowds and lower prices before the wet season fully sets in.

April & May; The Long Rainy Season

April and May bring the long rains, the wettest period of the year in Lamu. Heavy showers and higher humidity dominate, and the sea can become rougher with changing currents. Winds are generally light, though squalls can occur during storms.

These months are the quietest time to visit, perfect for those seeking solitude and a slower pace of life.

June; Lush Landscapes and Calmer Seas

By June, the long rains ease and the island bursts into vivid green. The Kusi winds — strong south-easterly trade winds — arrive, marking a new seasonal shift. These winds are fresh and brisk, averaging between 15 and 20 knots (around 28–37 km/h), and can make the sea choppy at times, particularly on exposed shores.

Still, between gusts and calm spells, the sea begins to settle and water clarity improves gradually. Fishing conditions become favourable again, especially in sheltered areas. June is also part of the low season, meaning you’ll enjoy quieter beaches and better value for accommodation.

July to September; The Long Dry Season

From July through to September, Lamu experiences its long dry season. Days are sunny, humidity is low and rainfall is rare. The Kusi winds continue through much of this period too, producing some swell offshore, but the breezes start to weaken in late August/ September.

July and August are among the busiest months on the island as it's such a good time to be on safari, so booking ahead is essential.

October & November; Mild Weather

The Kusi winds die down completely, giving way to light variable breezes and calm mornings. As such, early October is a very good time to travel, often offers crystal-clear water and excellent fishing. The combination of light winds and warm seas makes these months ideal for dhow sailing, paddle-boarding and relaxed beach days. By late October, rainfall increases all the way into November,.

December; Festive Season and Cultural Highlights

December marks the return of the Kaskazi winds, blowing softly from the north-east and ushering in the short dry season once more. These winds are gentle, and the weather is warm, bright and inviting — perfect for sailing and fishing. The sea temperature remains around 28 °C, with good visibility and calm conditions.

December is a busy period, with holidaymakers arriving for Christmas and New Year, creating a lively and colourful atmosphere. Accommodation fills quickly, so book early if you plan to visit during this time.
