Weather in May
Temperature
May's arrival coincides with a subtle temperature rise, moving from April's moderately hot 77.9°F (25.5°C) to a still warm 84.7°F (29.3°C). May's nights observe an average temperature of 63.9°F (17.7°C).Heat index
May's average heat index is calculated to be a tropical 93.2°F (34°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Consider that heat index readings are for situations in the shade and light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
