Temperature

The yearly lowest temperatures occur in July and August, averaging a high-temperature of 28.9°C (84°F).

Heat index

August's mean heat index is estimated at a torrid 35°C (95°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

June through August, with an average relative humidity of 83%, are the most humid months.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
