Understanding UV levels helps you take proactive measures against sunburn and long-term skin damage, particularly in a city known for its changeable weather.

With UV Index levels peaking at 2 around midday, it's essential to stay informed and protect yourself, ensuring you can enjoy the outdoors safely and confidently.

Throughout the year, UV Index levels fluctuate significantly, indicating varying risks for skin damage from sun exposure. The highest risk months are January, February, November, and December, where the UV Index reaches extreme levels (12-13) with a burn time of just 10 minutes. Following these months, March and October present very high risks with an index of 9 and 8 respectively, where individuals can burn in just 15 minutes.
