Weather in May

May in Diamondhead is traditionally recognized for the formal arrival of summertime heat. The leap from April's maximum temperature of 75.6°F (24.2°C) to May's 81.7°F (27.6°C) creates an air of anticipation for the approaching summer. This evolution accompanies an increase in relative humidity to 75%, making the surroundings noticeably muggy. While the average rainfall of 0.98" (25mm) is witnessed, the prevailing pressure remains uniform at 30" (762mm). Gusts traveling at 11.6mph (18.7km/h) add to the dynamic diversity of weather in May.

Temperature

The start of May brings a subtle rise in the average high-temperature, moving from a warm 75.6°F (24.2°C) in April to a still moderately hot 81.7°F (27.6°C). Diamondhead registers a consistent average low-temperature of 69.8°F (21°C) during May.

Heat index

May's heat index is estimated at a tropical 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.
Heat index determinations are made taking into account the shade and light air movements. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. 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.
