September weather forecast
Xlapak, Mexico

September, the first month of the autumn in Xlapak, is still a tropical month, with temperature in the range of an average low of 23.3°C (73.9°F) and an average high of 33.8°C (92.8°F).

Temperature

With the onset of September, the average high-temperature registers at a tropical 33.8°C (92.8°F), subtly different from August's 35°C (95°F). During the nights in September, an average low-temperature of 23.3°C (73.9°F) is observed.

Heat index

The average heat index in September is estimated at a blazing hot 50°C (122°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
Heat index determinations are made taking into account the shade and light air movements. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
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. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

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

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades.
