The Ultraviolet (UV) Index in Singapore reached extreme levels for more than one hour in the afternoon of March 30, just three days after it last hit such levels. According to the Meteorological Service Singapore (MSS), the UV Index reached 12, the extreme level, from 12.15 pm to 1.30 pm, and at 1.45 pm, it dropped to a very high level of 8.
| UV Index Level | Description | Recommended Protection |
|---|---|---|
| 0-2 | Low | No protection required. |
| 3-5 | Moderate | Wear sunglasses, a wide-brimmed hat, and apply SPF 15+ sunscreen. |
| 6-7 | High | Cover up with clothing, wear a hat and sunglasses, and apply SPF 30+ sunscreen. |
| 8-10 | Very High | Limit sun exposure between 10 am and 4 pm, wear long-sleeved clothing, a hat and sunglasses, and apply SPF 50+ sunscreen. |
| Above 11 | Extreme | Avoid sun exposure, seek shade, wear long-sleeved clothing, a hat and sunglasses, and apply SPF 50+ sunscreen. |
It is important to note that the UV Index levels may vary depending on the time of day, location, and weather conditions. It is essential to take appropriate precautions to protect oneself from the harmful effects of UV radiation. Always check the local UV Index forecast and take necessary measures to protect yourself.
The UV Index measures the level of solar UV radiation on the earth’s surface. The NEA advised the public to protect themselves from potential sunburn and monitor heat stress levels.
Heat stress occurs when the body can’t cool itself enough, leading to the buildup of excess heat. This may damage the body and increase the risk of heat cramps, heat exhaustion, and heatstroke.
Heat stress levels are based on Wet-Bulb Globe Temperature (WBGT), influenced by air temperature, humidity, wind, and solar radiation. The NEA collects WBGT data from nine sensor locations across Singapore to find out whether the heat stress level in the area is low, moderate, or high.
Two locations in Singapore, Choa Chu Kang and Kallang Practice Track, recorded high heat stress levels on March 30. During periods of high heat stress levels, the public is advised to minimize outdoor activities and take more frequent breaks under shelter. They should also drink more fluids, use an umbrella or hat and monitor their body for signs of heat-related illness.
It is essential to take precautions to protect oneself from the harmful effects of extreme UV levels and heat stress. The public should stay informed about the UV Index and heat stress levels in their area and take necessary measures to protect themselves.
