January is one of the top tourist season months since there is no rain. There can be up to 1 rainy day in some parts of the Gambia, but usually you won’t be lucky enough to see a drop of rain. Because nights can get quite cold, you will be able to breath in some fresh air in the evening and morning, which is very refreshing if you have been in the Gambia throughout the rainy season. This is also because the average humidity is still dropping, so you will sweat only in the middle of the day, when the sun stills get very hot, especially in direct sunlight. Don’t forget your sunscreen, because it is still very dangerous to get sunburns. Also, you should always have water with you.
The biggest challenge is to get to the soft white flesh and coconut water, since a) coconuts grow high up in the palm tree, b) fruit is protected by a thick fleshy skin and hard shell that covers the core. But if you are living in the tropics, you soon find a way to crack it. There are special techniques, that can be used to open it and to get to the coconut water without spilling it. Coconut gatherer is one of the jobs here in The Gambia. Mostly, young men and older boys learn how to climb the tree and then use machete to remove the outer husk. This is how coconuts as you probably know it are being sold in the markets and shops, also get ready for export.
The temperature of the sea water starts to drop to an average of 22°C which is still very enjoyable. But be aware of the waves, since coastal areas can be quite windy. With combination of the strong Atlantic currents, it is safer to stay in the shallow waters.
If you are planning to visit The Gambia, January is a perfect month. Average temperatures are around 25°C. You will still get enough of the sun, up to 10 hours per day of total 11,5 hours of daylight, usually accompanied with refreshing breeze from the sea.
