Weather in September
Temperature
Ribeiro Gonçalves notes the warmest temperatures in September, with a high average of 36.2°C (97.2°F) and a low of 22.9°C (73.2°F).Heat index
September's heat index is calculated to be a blisteringly hot 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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 are especially crucial for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
