Weather in May

May, the last month of the spring in Chiquimula, is another hot month, with an average temperature varying between 31.6°C (88.9°F) and 20.2°C (68.4°F).

Temperature

The dawn of May sees an average high-temperature of a still tropical 31.6°C (88.9°F), subtly contrasting with April's 32.3°C (90.1°F). During the nights in May, an average low-temperature of 20.2°C (68.4°F) is observed.

Heat index

In May, the average heat index is estimated at a blisteringly hot 40°C (104°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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 normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Humidity

In May, the average relative humidity is 73%.

Rainfall

In Chiquimula, during May, the rain falls for 21.6 days and regularly aggregates up to 97mm (3.82") of precipitation. In Chiquimula, during the entire year, the rain falls for 193.9 days and collects up to 636mm (25.04") of precipitation.

Sunshine

In May, the average sunshine is 10.5h.

UV index

The average daily maximum UV index in May is 6. A UV Index estimate of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the ordinary person.
Note: The maximum UV index, 6 during May, leads to the following recommendations:
Deflect overexposure. Sun protection is a necessity. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
