Published 2026-10-15 · Updated 2026-10-25

The High Season: October to March (Kaskazi)

This is the absolute best time for marine tours. Warm northeast winds bring calm, turquoise seas and underwater visibility reaching 25 to 30 meters. Ideal for families and underwater photography.

The Green Season: April to June (Long Rains)

Rainfall increases and sea swells are slightly higher, but lush green coastal scenery and uncrowded marine reefs offer peaceful experiences at great rates.

Humpback Whale Migration: July to September

During the cooler southern winter, massive pods of humpback whales migrate from Antarctica up through the Kenya coastal channel to mate and nurse their calves.
