Temperature

The average high-temperature in May, at a still tropical 30.9°C (87.6°F), reveals a modest deviation from April's 32.3°C (90.1°F). El Guabo experiences a nighttime temperature average of 23.8°C (74.8°F) during May.

Heat index

The heat index value for May is estimated at a blistering 41°C (105.8°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in 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. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

Note: A daily high UV index of 7 in May leads to these guidelines:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
