Temperature

May's onset records a minor alteration in the average high-temperature to a hot 34.8°C (94.6°F) from April's 36.2°C (97.2°F). Ban Wan's nighttime temperature in May drops to an average of 27.3°C (81.1°F).

Heat index

May's mean heat index is evaluated at a burning hot 45°C (113°F). Mind: Heat cramps along with heat exhaustion are anticipated. Heatstroke can develop with continued physical activity.
It is important to note that the heat index values are for shaded areas and light wind scenarios. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
