By staying informed about daily UV levels, you can enjoy the sunny days while protecting your skin—because a little awareness can go a long way!
The UV Index throughout the day offers a telling glimpse into solar intensity. Starting low at 07:00 with a UV Index of 0, it gradually rises, reaching 1 by 08:00 and 09:00. By 10:00, it inches up to 2, more noticeable as the day progresses. The peak sunlight unfolds around 12:00 to 14:00, where the index skyrockets to a maximum of 5.

The UV Index reveals significant seasonal variations in sun exposure, with the highest risk months occurring from January to March and November to December, where the index consistently falls within the extreme category (UV Index 14-15) and a mere 10 minutes of unprotected skin exposure can lead to burns. In contrast, April marks a transition to very high exposure (UV Index 9), allowing for 15 minutes before sunburn sets in, while May through July see a slight decrease in UV intensity, with May being high (UV Index 6) and a burn time of 25 minutes, and June and July maintaining moderate levels (UV Index 5, 30 minutes burnout). As summer fades into fall, August and September return to high and very high risk (UV Index 7-9, 15-25 minutes), suggesting that careful sun protection is vital, especially during these months. It's essential for both residents and visitors to remain vigilant about sun safety, particularly in high-risk months when exposure can quickly lead to skin damage. Regular application of sunscreen, wearing protective clothing, and seeking shade can significantly mitigate the risks associated with harmful UV rays.
