Weather in May
Temperature
Herbert perceives a slight temperature ascent during May, with average high-temperatures adjusting from a moderately hot 77°F (25°C) in April to a still warm 85.1°F (29.5°C). Herbert notes a substantial temperature decline from the daytime peaks throughout May, with an average nighttime temperature of 62.8°F (17.1°C).Heat index
In May, the average heat index is calculated to be a hot 93.2°F (34°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.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 'felt air temperature' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 highly important for children. 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.
