September and October bring Borie's highest average temperatures, reaching a high of 30.9°C (87.6°F).

Heat index

October's mean heat index is evaluated at an extremely hot 40°C (104°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As body temperatures escalate without effective heat release, one might face dehydration threats.
