The UV Index exhibits significant seasonal changes throughout the year, peaking during the summer months. From January (UV Index 2) to February (UV Index 4), exposure remains relatively low, making it a safer time for outdoor activities. However, starting in March (UV Index 6), the levels rise to high, and by April and May (both UV Index 8), it reaches very high, requiring increased sun protection measures. The July peak (UV Index 11) is classified as extreme, indicating a high risk of harm from unprotected sun exposure—burn time drops to just 10 minutes. The trend gradually decreases towards the fall, with September (UV Index 7) and October (UV Index 6) returning to high levels before tapering off again in the winter months. Residents and visitors should be especially cautious during July and August, applying sunscreen regularly, wearing protective clothing, and seeking shade, while during the lower UV months of January, February, and November, general precautions should still be observed.
