Temperature

September's onset records a minor alteration in the average high-temperature to a hot 33.8°C (92.8°F) from August's 35°C (95°F). In Uxmal, September nights cool down to an average of 23.3°C (73.9°F).

Heat index

September's mean heat index is evaluated at a burning hot 50°C (122°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
