Weather in May

May, the last month of the spring in Annadale, is also a moderately hot month, with an average temperature ranging between min 66.6°F (19.2°C) and max 84.9°F (29.4°C).

Temperature

May sees a marginal temperature increase, moving from a moderately hot 78.6°F (25.9°C) in April to a still warm 84.9°F (29.4°C). An average minimum temperature of 66.6°F (19.2°C) marks the month of May.

Heat index

The heat index in May is evaluated at a torrid 95°F (35°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
