Understanding the UV Index is crucial for residents of Kuhbanan, Iran, where the sun shines brightly in a BWk climate. With UV levels peaking at a dangerous 13 around noon, awareness is key to preventing sunburn and ensuring long-term skin health.

The UV Index presents a vibrant dance of intensity throughout the day. Starting at a mild 2 by 7:00 AM, the index gradually climbs, hitting a moderate 3 by 8:00 AM. As the sun ascends higher, the UV intensity spikes dramatically, reaching its peak at 12:00 PM with a striking 13. This marks the most hazardous period, urging outdoor enthusiasts to take precautions. Following noon, the UV Index begins to taper off; it drops to 10 by 2:00 PM, then gracefully declines to a more manageable 2 by 5:00 PM. As the day winds down, the UV Index settles at a gentle 1 by 7:00 PM, making for safer evening activities. Whether basking in midday sunlight or enjoying a twilight stroll, awareness of these UV changes ensures safe outdoor enjoyment.
