Heat index

The average heat index in April is evaluated at a torrid 39°C (102.2°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The months with the highest humidity are April and May, with an average relative humidity of 80%.

Rainfall

The month with the most rainfall is April, when the rain falls for 22 days and typically aggregates up to 89mm (3.5") of precipitation.

UV index

Note: During April, 7 as the daily maximum UV index converts into the following advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
