Weather in May
Temperature
May's arrival brings a slight change in high-temperatures, adjusting from an agreeable 72.9°F (22.7°C) in April to a warm 81.1°F (27.3°C). The average nighttime temperature in Houston lowers to a comfortable 61.9°F (16.6°C) throughout May.Heat index
The heat index value during May is evaluated at a hot 86°F (30°C). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Heat index evaluations are typically in the context of light winds and shaded environments. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
