May weather forecast
Mombasa, Kenya

May proffers the peak of the rainy season in Mombasa, showing a significant surge in precipitation to 48mm (1.89") from 35mm (1.38") in the previous month. City dwellers pull out their raincoats and umbrellas as the city embraces the downpour. As the month progresses, the rain tends to become lighter, setting stage for June.

Temperature

The transition into May reveals an average high-temperature of a warm 29.2°C (84.6°F), mirroring a close resemblance to April. During the May nights, an average temperature of 24.1°C (75.4°F) is observed.

Heat index

May's heat index is estimated at a sweltering 35°C (95°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
