Staying informed about the UV Index is crucial for residents and visitors in So Phisai, Thailand, where sunny days and high temperatures are the norm. Understanding UV levels can significantly impact sunburn prevention and overall skin health, especially given the region's climate, classified as Aw, which contributes to increased UV exposure throughout the year. With UV Index values soaring to a maximum of 14 around midday, it’s essential to take preventive measures by planning outdoor activities wisely and applying sunscreen accordingly to protect against harmful effects.
The UV Index tells a compelling story throughout the day, starting off with a gentle 1 at 7:00 AM. As the sun ascends, it charges up rapidly, reaching a moderate 4 by 8:00 AM. The intensity peaks at 12:00 PM with an intense 14, suggesting that this is the time to seek shade and take precautions against sunburn. The index gradually declines thereafter, dropping to 6 by 3:00 PM, and further down to a safe 1 at 5:00 PM. As evening sets in, the UV rays diminish, leaving a 0 at 7:00 PM. It's clear: the midday hours are when the sun is most powerful, so plan accordingly to protect your skin!

During the year, UV index levels exhibit significant seasonal changes, with the highest readings occurring in the spring and summer months. The months of February through October are particularly critical, displaying extreme UV levels where the burn time averages just 10 minutes. Notably, July reaches the peak UV index of 15, categorizing it as one of the highest risk months alongside March, April, May, August, and September. Residents and visitors are strongly advised to take precautions during these high-risk months by seeking shade, wearing protective clothing, and applying broad-spectrum sunscreen to reduce sunburn and long-term skin damage. As the year progresses into November and December, the UV index decreases to very high, but caution is still warranted as the burn time increases slightly.
