Heat index

The heat index value during September is computed to be a blisteringly hot 105.8°F (41°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly relevant to babies and toddlers. 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 natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As body temperatures escalate without effective heat release, one might face dehydration threats.

The months with the highest humidity are July through September, with an average relative humidity of 78%.

Take precautions against overexposure. Protection against sun damage is needed. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
