Temperature

November's advent notes a subtle adjustment in average high-temperature to a still tropical 30.6°C from October. In Singapore, the November nights cool down to an average low of 23.7°C.

Heat index

The heat index value for November is computed to be a blistering 42°C. Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
Heat index guidelines indicate values are for light wind scenarios and shaded regions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

Take every vital safeguard, as unprotected skin and eyes may suffer burns rapidly. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. A sunscreen boasting a minimum SPF of 30 should be generously applied and reapplied even on cloudy days, post swim or outdoor exercise. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
