Weather in May
Temperature
The commencement of May introduces an average high-temperature of a moderately hot 28.8°C (83.8°F), closely mirroring the preceding month. A modest decline from daytime high temperatures is noticed in May, marking the average low at 24.4°C (75.9°F).Heat index
Throughout May, the heat index is appraised at a tropical 34°C (93.2°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
