Chiltiupan, El Salvador

May takes a dramatic turn from dry to wet, with a significant upsurge in rainfall and relative humidity. The days become progressively shorter, and clouds begin to dominate the Chiltiupan sky. Yet, its persistent warm weather does not waver. This month experiences a drastic increase in rainfall, with a precise measurement of 234mm (9.21"), making it the wettest month of the year. The heavier rains and decline in sunshine hours tend to cool off the surroundings, offering a much-needed respite to the townsfolk.

May's onset sees an average high-temperature of a still hot 30.9°C (87.6°F), exhibiting a slight fluctuation from the previous month. In the month of May, the average low-temperature usually rests at a pleasant 22.7°C (72.9°F).

Heat index

In May, the heat index is evaluated at a sweltering 39°C (102.2°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
