Heat index

The heat index value during September is calculated to be a blisteringly hot 42°C (107.6°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The months with the highest humidity are July through September, with an average relative humidity of 82%.

Rainfall

UV index

The months with the highest UV index are March through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for the average person.
Note: In September, the maximum UV index of 7 suggests this advice:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
