Weather in April
Temperature
The coldest period is April, when temperatures fluctuate between an average high of 29.7°C (85.5°F) and a low of 23.3°C (73.9°F).Heat index
The average heat index in April is appraised at a blistering 40°C (104°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Resist extreme sun exposure. Guarding against solar damage is essential. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
