Temperature

In April, Belize City experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 29.5°C (85.1°F) in March to a hot 30.7°C (87.3°F). During the nights in April, Belize City observes an average low-temperature of 23.1°C (73.6°F).

Heat index

For most parts of April, the heat index is computed to be a torrid 39°C (102.2°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold great significance to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

With an average relative humidity of 77%, April is the least humid month.

Rainfall

April is the month with the least rainfall. Rain falls for 3.9 days and accumulates 52mm (2.05") of precipitation.

UV index

March through September, with an average maximum UV index of 12, are months with the highest UV index. A UV Index value of 11, and more, symbolizes an extreme threat to health from exposure to the Sun's UV radiation for the ordinary person.
Note: In April, the maximum UV index of 12 suggests this advice:
Adopt all important safety measures, unprotected skin may burn rapidly. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Directly after outdoor activities or swimming, a broad-spectrum sunscreen with SPF 30+ should be applied generously and reapplied frequently. Caution! The mirror effect of sand and water ups the UV radiation strength.
