Heat index

Throughout April, the heat index is calculated to be an extremely hot 41°C (105.8°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
For clarity, heat index numbers account for light winds and areas under shade. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The average relative humidity in April is 79%.

Rainfall

UV index

The months with the highest UV index are January through September, November and December, with an average maximum UV index of 6. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV rays for the average person.
Note: In April, a regular UV index of 6 translates into these guidelines:
Deter overexposure. Protecting against the sun's effects is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
