The advent of September denotes an average high-temperature of a still hot 30.5°C (86.9°F), subtly different from August's 30.3°C (86.5°F). Cortés experiences an average nighttime temperature of 23.7°C (74.7°F) in the month of September.

Heat index

The heat index value for September is computed to be an extremely hot 40°C (104°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In Cortés, the average relative humidity in September is 81%.

Note: The UV index of 7 during September translates into the following guidance:
Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
