Temperature

The transition from April to May brings a subtle temperature rise, with average high-temperatures increasing from a warm 25.6°C (78.1°F) to a still moderately hot 28.8°C (83.8°F). Nighttime temperatures in Lin Ma Hang during May report a consistent average of 24.5°C (76.1°F).

Heat index

Throughout May, the heat index is evaluated at a very hot 35°C (95°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.
The standards for the heat index are set for locations in shade and under light breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes.

Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
