April weather forecast
Kiswa, Uganda

April, like March, in Kiswa, Uganda, is another warm spring month, with an average temperature varying between 17.4°C (63.3°F) and 29°C (84.2°F).

Temperature

With the arrival of April, Kiswa notices a mild change in the average high-temperature, sliding from March's tropical 32.1°C (89.8°F) to a moderately hot 29°C (84.2°F). During April, Kiswa's temperature averages to a refreshing 17.4°C (63.3°F) at night.

Heat index

In April, the average heat index is calculated to be a sweltering 35°C (95°F). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Humidity

In April, the average relative humidity is 81%.

Rainfall

Shield from overexposure. Defense against sun-related harm is required. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
