Temperature

The warmest month is June, with an average high-temperature of 32.4°C (90.3°F) and an average low-temperature of 26.8°C (80.2°F).

Heat index

June's mean heat index is estimated at a blazing hot 45°C (113°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
