Understanding the UV Index is crucial for residents and visitors in Bandar-e Emam Khomeyni, Iran, where the sun's powerful rays can pose significant health risks. With a typical climate classified as BWh, the region experiences intense sunlight, especially during midday hours when UV levels peak at an alarming 11, indicating a high potential for skin damage. Recognizing these UV levels is essential for preventing sunburn and long-term skin health issues, allowing you to enjoy your outdoor activities while staying safe. By staying informed about the daily UV Index, you empower yourself to take proactive measures to protect your skin from harmful exposure.
At dawn, the UV Index starts at a gentle 1 and gradually rises as the sun climbs higher in the sky.

As the seasons change, so does the UV Index, which significantly impacts sun safety for visitors and residents. From January to February, UV exposure transitions from moderate to high, with burn times decreasing from 30 to 25 minutes. The spring months of March and April see a sharp increase to very high levels (UV Index 9 and 10), demanding precautions as burn times shrink to just 15 minutes. May through July presents the highest risks, classified as extreme (UV Index 11), where protective measures are critical as burn times drop to just 10 minutes. As summer fades into August and September, conditions remain very high, with burn times back to 15 minutes. By October, UV exposure reduces to high, before settling back into moderate levels in November and December. Advising residents and visitors to utilize sunscreen, wear protective clothing, and limit sun exposure during these high-risk months—particularly from March to July—will help prevent harmful effects from the sun.
