APRIL HAS been an unusually hot and cruel month with the ultraviolet radiation hovering between medium and high risk, and now threatening to reach the danger zone mark. Rising temperatures have put Pune at a high-risk zone with the ultraviolet rays on Tuesday crossing the value 10, which is extremely dangerous.
“One could feel the scorching heat this afternoon,” said Dr Gufran Beig, chief project scientist of System of Air Quality and Weather Forecasting Research (SAFAR), which facilitates information on air quality, weather and radiation (ultra violet index). The ultraviolet index, set up by SAFAR at the Indian Institute of Tropical Meteorology, has registered values that range between 8 and 9 throughout April and on Tuesday it crossed 10.
Beig urged citizens to avoid direct sun exposure explaining that there was relatively less pollution due to the dry and clear weather. There is no barrier as such for the sun’s rays and hence, one can feel the scorching heat like Tuesday’s, he pointed out.

Overexposure to the sun’s ultraviolet (UV) radiation can cause immediate effects such as sunburn and long-term problems such as skin cancer and cataracts. The UV Index, which was developed by city-based Indian Institute of Tropical Meteorology, Pune, provides important information to help you plan your outdoor work to prevent overexposure to the sun’s rays in Pune city areas.
Medium risk means that the sun is not very dangerous in UV, but you should avoid being in direct sunlight for more than 2 hours. High risk means sun is becoming harmful in UV and a direct continuous exposure to sun for 1 hour is sufficient to get a sun burn. Dangerous/ Extreme risk means you could burn in 30 to 60 minutes. The UV index is effectively a rough measure of the amount of harmful ultraviolet radiation in the sunlight reaching the Earth’s surface at a given location, where 0 indicates no risk and 1-4 indicates a low risk of overexposure and 11+ signifies an extreme risk.
