Temperature

The transition into July notes an average high-temperature of a still hot 31.2°C (88.2°F), revealing a mild distinction from the 31°C (87.8°F) in June. In July, Chunchucmil's temperature tends to fall to an average low of 25.5°C (77.9°F) during the night.

Heat index

For most parts of July, the heat index is calculated to be a blistering 40°C (104°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
