Weather in May
Temperature
In May, Weslaco experiences a minor shift in meteorological conditions with average high-temperatures marked at a still tropical 90.9°F (32.7°C), closely mirroring the climate in April. Weslaco, during May nights, observes an average temperature of 72.9°F (22.7°C).Heat index
Throughout May, the heat index is computed to be a blisteringly hot 109.4°F (43°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.Heat index details are generally centered around shaded locations and a mild breeze. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
