Weather in May
Temperature
May's onset brings a subtle temperature rise, moving from a warm 76.5°F (24.7°C) in April to a still moderately hot 82.9°F (28.3°C). Grand Bay records an average temperature drop to an agreeable 69.1°F (20.6°C) in May.Heat index
For most parts of May, the heat index is computed to be a tropical 89.6°F (32°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
