Weather in May
Temperature
In Opichén, May is the warmest month, with temperatures averaging a high of 35.4°C (95.7°F) and a low of 24°C (75.2°F).Heat index
In May, the heat index is appraised at a life-threatening hot 48°C (118.4°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
