Traveller notes on Watamu in January
Notes from nearby Mombasa (87 km away)
Watamu doesn't have its own notes for January yet — these are about Mombasa, close enough to share the season.
Mombasa's forum calls January genuinely hot — even locals describe it as hot and humid — though a sea breeze takes the edge off. Regulars recommend high-SPF sunscreen and staying under a parasol or tree during peak midday sun, since the equatorial intensity here is stronger than many visitors expect coming from the Caribbean.
