Weather in May

May, the last month of the spring in Wylie, is a warm month, with an average temperature fluctuating between 80.8°F (27.1°C) and 63.7°F (17.6°C).

Temperature

Wylie's May weather indicates a minor ascent in high-temperatures, adjusting from a pleasant 73°F (22.8°C) in April to a warm 80.8°F (27.1°C). An average low-temperature of 63.7°F (17.6°C) is noted during the nights in May.

Heat index

May's heat index is computed to be a hot 86°F (30°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.

Inhibit overexposure. Warding off sun damage is of utmost importance. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
