Weather in May
Temperature
The arrival of May sees an average high-temperature of a still hot 31.4°C (88.5°F), hardly diverging from April's 31°C (87.8°F). During May, Sabana Grande witnesses a consistent average low-temperature of 21.1°C (70°F).Heat index
The heat index value during May is evaluated at a blistering 40°C (104°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for the average person.Note: The UV index of 7 in May translates into these instructions:
Take precautions and adopt sun safety practices. Protection against sunburn is obliged. 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. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
