This month still holds a high level of precipitation, albeit less than the record level of May, receiving rainfall largely due to the extended rainy season. It’s worth noting that the UV index diminishes slightly to 11 units this month. Despite the receding daylight hours to 12.5, the days remain reasonably long. The sea temperature decreases to 28°C (82.4°F), denoting cooler conditions than the preceding months.Temperature
Cotonou, Benin, experiences an average high-temperature of a moderately hot 29.2°C (84.6°F) with the onset of June, subtly varied from May's 31°C (87.8°F). In the month of June, the nighttime temperature dips to a steady average of 23.7°C (74.7°F).Heat index

Heatstroke may result from lengthy activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
