The last month of the spring, May, is another hot month in Champerico, Guatemala, with an average temperature ranging between min 26.8°C (80.2°F) and max 32.7°C (90.9°F).

Temperature

The commencement of May records an average high-temperature of a still hot 32.7°C (90.9°F), barely varying from April's 32.8°C (91°F). Champerico observes an average low-temperature of 26.8°C (80.2°F) during May nights.

Heat index

The heat index value for May is computed to be a blisteringly hot 42°C (107.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for 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.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Stay aware! UV radiation is magnified when reflecting off sand and water.
