May weather forecast
Amatitán, El Salvador

The last month of the spring, May, is also a hot month in Amatitán, El Salvador, with temperature in the range of an average low of 22.6°C (72.7°F) and an average high of 31.8°C (89.2°F).

Temperature

The commencement of May records an average high-temperature of a still tropical 31.8°C (89.2°F), barely varying from April's 33.4°C (92.1°F). During May, the nighttime temperature averages to a pleasant 22.6°C (72.7°F).

Heat index

May's average heat index is evaluated at a blistering 42°C (107.6°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

In May, the average relative humidity is 76%.

UV index

May through December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high threat to health from unprotected exposure to Sun's UV rays for average individuals.
Note: The daily high UV index of 6 during May translates into the following recommendations:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
