Weather in May
Temperature
The start of May brings a subtle rise in the average high-temperature, moving from a warm 76.6°F (24.8°C) in April to a still moderately hot 84°F (28.9°C). In the month of May, the nighttime temperature dips to a steady average of 65.3°F (18.5°C).Heat index
The heat index for May is computed to be a tropical 93.2°F (34°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index values are typically calculated for conditions of shade and a light breeze. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
