The rains are plentiful, but the rainy seasons are reversed between the mainland and the islands.
In the mainland, known as Rio Muni, precipitation is above 2,000 millimetres per year; the rains occur from September to May, while there's a dry season from June to August; in the north (see Bata) the rains also decrease slightly from December to February, while in the south (see Cogo) it rains a lot even from December to February. The amount of sunshine is never good anyway, and it is even scarcer in the driest months.
Here is the average precipitation in Bata.

In the island of Bioko, precipitation remain below 2,000 in per year in the capitale Malabo, while it exceeds 3,000 mm per year in the rest of the island; here the dry season runs from December to February, although it's more pronounced in the northern part, where the capital Malabo is located, while the rainiest period is from May to October.

In the winter months, a hot dry wind from the mainland can blow. Here, too, the sky is often cloudy, especially from June to August. Malabo is one of the least sunny capitals in the world, being usually cloudy, or even foggy. It follows that the vegetation is lush.
In Bioko, at no great distance from Malabo, there is the highest peak of Equatorial Guinea, Pico Basilé, 3,011 metres high. The slopes of the volcano are very rainy, but they protect the capital, located on the north coast of the island, in the period from July to October, when it rains more than in the capital also in the east and south coasts of the island.
In the southernmost island of Annobón, the rainfall pattern is similar to that of the mainland, with a dry season from June to September. Here, too, the sky is often cloudy.


The sea in Equatorial Guinea is warm all year round, as you can see in the following table.
