UV Index Today - Real-Time UV Forecast & Sun Protection Guide

What is the UV Index?

The UV Index is an international standard measurement of ultraviolet radiation from the sun at a particular place and time. The UV Index scale ranges from 0 to 11+, with higher numbers indicating greater risk of harm from unprotected sun exposure. Understanding today's UV index helps you plan appropriate sun protection and reduce skin cancer risk.

Current UV Index & Forecast

Check the real-time UV index for your location above. Our UV tracker provides hourly UV forecasts for the next 24 hours, showing you when UV radiation peaks and when it's safest to be outdoors. The interactive UV graph displays color-coded alerts: green for low UV (0-2), and orange for moderate to very high UV (3-11+).

UV Index Scale & Protection Levels

• UV Index 0-2 (Low): Minimal sun protection needed. Safe for most outdoor activities.
• UV Index 3-5 (Moderate): Protection required. Wear sunscreen SPF 30+, sunglasses, and consider a hat.
• UV Index 6-7 (High): Extra protection essential. Seek shade during midday hours, wear protective clothing.
• UV Index 8-10 (Very High): Take full precautions. Minimize sun exposure between 10 AM and 4 PM.
• UV Index 11+ (Extreme): Maximum protection required. Avoid sun exposure during peak hours.

When is UV Radiation Highest?

UV radiation is typically highest between 10 AM and 4 PM, with peak intensity around solar noon (approximately 12-2 PM depending on your location and daylight saving time). The UV index graph above shows your local UV forecast throughout the day, helping you plan outdoor activities during safer hours with lower UV exposure.

Sun Protection Recommendations

Protect your skin from harmful UV radiation with these evidence-based recommendations:

• Apply broad-spectrum sunscreen SPF 30-50+ every 2 hours and after swimming
• Wear UPF-rated protective clothing, wide-brimmed hats, and UV-blocking sunglasses
• Seek shade during peak UV hours (10 AM - 4 PM)
• Check the UV index daily before outdoor activities
• Protect children and babies - their skin is more sensitive to UV damage
• Don't rely on cloud cover - up to 80% of UV rays penetrate clouds
• Use extra caution near water, snow, and sand which reflect UV radiation

Location-Based UV Tracking

This UV index tool automatically detects your location to provide accurate, localized UV forecasts. UV levels vary by geographic location, altitude, season, time of day, and weather conditions. Locations closer to the equator, at higher elevations, or with less atmospheric pollution typically experience higher UV radiation levels.

Why Monitor UV Index Daily?

Regular UV index monitoring helps prevent sunburn, premature skin aging, and reduces skin cancer risk. Cumulative UV exposure over your lifetime is the primary cause of melanoma and non-melanoma skin cancers. By checking today's UV index and following sun safety guidelines, you can enjoy outdoor activities while minimizing harmful UV exposure.
