Temperature

Heat index

For April, the heat index is calculated to be a torrid 39°C (102.2°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Humidity

The average relative humidity in April is 86%.

Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
