Weather in April
Temperature
The arrival of April coincides with an average high-temperature of a still moderately hot 27.8°C (82°F), indicating a minimal shift from March's 27.2°C (81°F). An average temperature of 23.6°C (74.5°F) is logged during the nights of April, a small step down from daytime highs.Heat index
April's average heat index is computed to be a hot 31°C (87.8°F). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.

Shun overexposure. Protection from sun ravages is indispensable. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Attention! UV strength is notably upped by the reflection of sand and water.
