Weather in May
Temperature
The shift into May is marked by a modest rise in the average high-temperature, moving from April's pleasant 72.5°F (22.5°C) to a warm 81.1°F (27.3°C). In Grapevine, an average nighttime temperature of 61.7°F (16.5°C) is expected during May.Heat index
May's average heat index is appraised at a hot 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
