Weather in May
Temperature
The start of May signals a slight increase in the average high-temperature, moving from a moderately hot 76.6°F (24.8°C) in April to a still warm 84.7°F (29.3°C). The mean low-temperature during May nights is a comfortable 63.5°F (17.5°C).Heat index
In May, the average heat index is appraised at a tropical 93.2°F (34°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially crucial for babies and toddlers. 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.
