May weather forecast
Ahuachapan, El Salvador

May marks the peak of the rainy season with an overwhelming 156mm (6.14") of average rainfall, spanning across 24 out of 31 days. It becomes the wettest month in Ahuachapan, a far cry from its dry start at the beginning of the year. Consequently, humidity levels rise, culminating in a rather humid and wet atmosphere that persists throughout this entire month. The weather shifts, veering from the norm that residents have become accustomed to during the preceding months.

Temperature

Ahuachapan's May showcases an average high-temperature of a still tropical 30.9°C (87.6°F), hardly distinct from April's 32.6°C (90.7°F). Ahuachapan's average low-temperature during May nights is observed to be an agreeable 21.7°C (71.1°F).

Heat index

For most parts of May, the heat index is estimated at a torrid 39°C (102.2°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Note: The UV index of 6 during May translates into the following guidance:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
