Heat index

September's average heat index is computed to be a fiery hot 38°C (100.4°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Guard oneself from overexposure. Defence against sun injury is vital. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
