Best Time to Visit Watamu: Weather, Seasons and Travel Tips

Watamu is warm all year, so the real question behind the best time to visit Watamu is not temperature, it is rain, wind and how busy the coast gets. Here is what the seasons actually look like, month by month.

Watamu’s climate at a glance

Watamu has a hot tropical climate with a distinct dry season rather than four separate seasons. Daytime temperatures typically sit between 27°C and 32°C year-round, with warm, swimmable ocean water throughout. What changes through the year is rainfall, humidity and how many other travellers you will be sharing the beach with.

Dry season: January–February and August–September

These are Watamu’s most reliable months for sunshine, with around nine hours of sun a day and minimal rainfall. January and February combine dry weather with warm temperatures, making this the busiest and most popular stretch for beach holidays. August and September are similarly dry but slightly cooler, a good compromise if you want dependable weather without the peak-season crowds of the new year period.

The long rains: April–May

April and May are Watamu’s wettest months, with May typically the rainiest of the year. Rain tends to fall in heavier, shorter bursts rather than all day, but this is generally considered the low season, hotels are quieter and rates are often lower, but you should expect some disrupted beach days and rougher seas for watersports.

The short rains: November

November brings a secondary, lighter rainy period, sometimes called the short rains. It is milder than April and May, with rain typically arriving in shorter spells, and is often a reasonable compromise for travellers who want lower rates and fewer crowds without committing to the wettest months.

June, July, October and December

These transitional months sit between the rainy and dry periods. Rainfall is moderate and inconsistent, but overall conditions are generally good for a beach holiday, with July in particular overlapping with the start of Watamu’s main excursion season for trips like Love Island and Mida Creek.

Best time for specific activities

Snorkelling and diving: calmer seas during the dry months (January–February, August–September) generally mean better underwater visibility.
Kitesurfing: wind conditions at Garoda Beach are consistent for much of the year, but the dry season pairs the wind with the most reliable sunshine.
Love Island excursions: guided tours typically run daily from July through March, so plan around this window if the reef crossing is a priority.
Budget travel: April, May and November bring the lowest rates and quietest beaches, at the cost of a higher chance of rain.

A quick month-by-month summary

January–February: dry, sunny, busy, warm.
March: transitional, rain increasing toward the end of the month.
April–May: wettest months, low season, quieter and cheaper.
June: drying out, good value.
July: mostly dry, cooler, excursion season begins.
August–September: dry, sunny, slightly cooler than January-February.
October: transitional, generally pleasant.
November: short rains, lighter and shorter than April-May.
