August weather forecast
Seletar, Singapore

August brings consistent weather patterns revealing similar conditions to July with slightly warmer temperatures. Lack of heavy rainfall coupled with steady wind speeds make it ideal for indulging in outdoor water sports. Although the UV index persists at 7, longer sunshine hours give an ample opportunity for sun seekers. The humidity sees a marginal decrease, making this month more pleasant for longer durations of outdoor activities. Given the steady visibility and dry weather, August could be an opportune time for photography enthusiasts to capture Seletar’s beauty.

Temperature

August's weather displays an average high-temperature of a still tropical 31.3°C (88.3°F), slightly varied from July's 31.1°C (88°F). Seletar's August nights cool down to an average low-temperature of 26°C (78.8°F).

Heat index

In August, the average heat index is appraised at a blistering 40°C (104°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

In August, the average relative humidity is 74%.

UV index

January through November, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for ordinary individuals.
Note: The maximum UV index of 7 during August leads to these instructions:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
