Weather in April

The month of April in the British Indian Ocean Territory further advances the shift from the wet to the dry season. Precipitation levels continue to decrease, with an average rainfall of about 150mm (5.91"), a slight reduction from March. This decreasing trend signifies the close of the monsoon season and the onset of drier conditions.

Average temperatures in April remain fairly constant, with a range from 26°C (78.8°F) to 30°C (86°F), consistent with previous months. The relative humidity remains high, typically above 80%, which can make the actual temperatures feel warmer than they are.

Comparing April with March, there's a visible continuation of the decreasing trend in rainfall, while temperatures and humidity levels remain nearly constant. Looking ahead to May, the territory further progresses towards the drier season with even less rainfall, while the temperatures and humidity remain consistent.

In line with the rest of the territory, the largest settlement, the U.S. naval support facility on Diego Garcia, experiences a similar weather pattern in April. There are no notable cities in the British Indian Ocean Territory as it remains largely uninhabited.

As the rainfall continues to decrease in April, conditions for outdoor activities improve. This, coupled with the still thriving marine life, makes April a good time for visitors interested in exploring the islands and the underwater ecosystem. The relatively stable temperatures and persistently high humidity also provide good conditions for the lush vegetation on the islands, adding to the territory's natural beauty.
