Weather in May
Temperature
A soft shift in the average high-temperature is noticeable in May, transitioning from 73.6°F (23.1°C) in April to a still moderately hot 81°F (27.2°C). Williamson's average low-temperature for the month of May records at a refreshing 60.8°F (16°C).Heat index
May's mean heat index is calculated to be a tropical 86°F (30°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. 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 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
