Understanding the UV Index in Rezvanshahr, Iran, is essential for maintaining skin health and preventing sunburn. With maximum UV exposure typically occurring during midday hours, locals and visitors alike must stay informed about daily UV levels to protect themselves effectively.

As the seasons change, so do the UV Index levels, which indicate varying risks of skin damage from sun exposure. High-risk months for UV exposure occur from March to September, with especially extreme readings in May (UV Index 11) and consistently very high levels in June and July (UV Index 10). During these months, the burn time significantly decreases, ranging from just 10 to 15 minutes, meaning that even brief sun exposure can lead to skin damage. Visitors and residents are advised to take precautions during these peak months by wearing sunscreen with high SPF, protective clothing, and seeking shade, especially during midday when the sun is strongest. As autumn sets in, the UV Index gradually lowers, with October offering a high risk, easing back to moderate levels in winter months. It’s essential to remain vigilant year-round, as skin protection is crucial in all seasons.
