July weather forecast
Mapaki, Sierra Leone

As Mapaki forges ahead in the heart of the monsoon, July emerges as the peak of this wet period. A transitioning landscape from vibrant green to a darker monsoon-soaked hue displays a clear reflection of the weather. August presents similar patterns with the monsoon's grip tightening onto the city, offering little reprieve. The showstopper of July is the rainfall reaching an overwhelming average of 284mm (11.18"), making it the rainiest month of the year. Rollercoaster of downpours, sultry days, and serene nights, July stands out amongst the rest.

Temperature

The average high-temperature is a warm 28.7°C (83.7°F) in July, hardly different from the 31.2°C (88.2°F) recorded in June. Mapaki reports a consistent average low-temperature of 22°C (71.6°F) throughout July nights.

Heat index

The heat index value during July is estimated at a sweltering 36°C (96.8°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
