Weather in May
Temperature
The weather during May records an average high-temperature of a still tropical 31.8°C (89.2°F), closely mirroring the preceding month. Throughout the month of May, Santiago Texacuangos observes an average nighttime temperature of 22.6°C (72.7°F).Heat index
May's average heat index is calculated to be an extremely hot 42°C (107.6°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
Humidity
The average relative humidity in May is 76%.Rainfall
May is the month with the most rainfall. Rain falls for 26.9 days and accumulates 267mm (10.51") of precipitation.Daylight

Sunshine
The average sunshine in May is 10.7h.UV index
The months with the lowest UV index are May through December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: In May, the average maximum UV index of 6 translates into the following recommendations:
Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
