August weather forecast
Sierra Leone

In Sierra Leone, August continues the pattern of intense rainfall seen in the peak months of the rainy season. Rainfall levels remain high, typically ranging between 450mm (17.72") to 550mm (21.65"), rendering August as one of the wettest months of the year. Consistent with the preceding months, heavy rain showers are commonplace and can occur at any time of day or night.

Despite the high levels of precipitation, temperatures persist in their warm trend, generally fluctuating between 23°C (73.4°F) to 30°C (86°F) across the country. The coastal areas, including Freetown, maintain these temperatures coupled with high humidity. The central and eastern regions, due to their higher altitude, experience similar daytime temperatures but cooler evenings.

When compared to July, August experiences similar, if slightly reduced, levels of precipitation. However, it still constitutes part of the peak of the rainy season, with the volume of rainfall only beginning to diminish in the following month of September.

While the heavy rainfall can potentially cause logistical challenges and impact outdoor activities, it also perpetuates the lush greenery that characterises the Sierra Leonean landscapes during this time. For those undeterred by the wet conditions, August provides a glimpse into the country’s vibrant ecosystems and biodiversity at its most lush and active. Nevertheless, travellers planning a visit during this time should come well-prepared for the wet conditions and potential travel disruptions.
