Temperature

March, August through October represent the warmest period, with an average high-temperature of 30.6°C (87.1°F).

Heat index

September's mean heat index is appraised at a blistering 40°C (104°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Note that heat index values are valued for light wind and location in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. 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. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
