Temperature

The advent of April sees the average high-temperature at a still warm 29.6°C (85.3°F), subtly shifted from March's 28.4°C (83.1°F). Throughout April, the average low-temperature records at a pleasant 21.4°C (70.5°F).

Heat index

Throughout April, the heat index is computed to be a sweltering 35°C (95°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Thinking about the heat index, one should account for its values in shaded areas with gentle 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 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. 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. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

The average relative humidity in April is 76%.

Note: The UV index of 7 during April leads to these advisories:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. 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. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
