Weather in May
Temperature
May witnesses a subtle temperature ascent, adjusting from a moderately hot 25.1°C (77.2°F) in April to a still warm 28.3°C (82.9°F). Throughout May, a minimal difference from peak daytime temperatures is noted, marking a steady low-temperature average of 24.7°C (76.5°F).Heat index
May's mean heat index is estimated at a tropical 33°C (91.4°F). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
