April weather forecast
Sussex, Sierra Leone

The arrival of April brings about a striking change in the landscape of Sussex weather patterns. There is a significant increase in the quantity of rainfall, soaring from 6mm (0.24") in March to 18mm (0.71") in April. Noteworthy is the rise in relative humidity to 74%, hinting at an escalation in the rainy season impact. Despite this change, temperatures remain comfortably warm and inviting for outdoor activities. Expect occasional showers in April, giving a respite from the sunshine and warmth.

Temperature

The onset of April in Sussex brings an average high-temperature of a still tropical 30.8°C (87.4°F), nearly matching the March temperature. In April, in Sussex, the average low-temperature is a warm 25.3°C (77.5°F).

Heat index

During April, the heat index is evaluated at a very hot 38°C (100.4°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

In Sussex, the average relative humidity in April is 74%.

UV index

January through June, September through December, with an average maximum UV index of 7, are months with the highest UV index in Sussex. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for average individuals.
Note: A typical high UV index of 7 in April suggests the following recommendations:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
