Weather in May

May, the last month of the spring in Port Vincent, is also a moderately hot month, with an average temperature fluctuating between 66°F (18.9°C) and 84.7°F (29.3°C).

Temperature

With the onset of May, the average high-temperature subtly transitions from 78.4°F (25.8°C) in April to a still moderately hot 84.7°F (29.3°C). May is noted for a mean low-temperature of 66°F (18.9°C).

Heat index

May's heat index is evaluated at a fiery hot 95°F (35°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
