May weather forecast
Atescatempa, Guatemala

May, the last month of the spring in Atescatempa, is another tropical month, with an average temperature ranging between max 31.1°C (88°F) and min 20.7°C (69.3°F).

Temperature

May's beginning signals an average high-temperature of a still hot 31.1°C (88°F), barely different from April's 33.2°C (91.8°F). Atescatempa observes an average low-temperature of 20.7°C (69.3°F) during May nights.

Heat index

Throughout May, the heat index is estimated at a blisteringly hot 40°C (104°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

UV index

The months with the highest UV index are January through August, October through December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for ordinary individuals.
Note: In May, a daily maximum UV index of 6 leads to the following instructions:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
