UV Index Today is a real-time UV radiation monitoring service that displays current UV index values, 3-hour forecasts, and offers customized sun protection guidelines based on the measured intensity.
What is UV Index Today?
UV Index Today is a free web application available at uvindex.cc that provides live UV index readings for any location. It takes location data (via auto-detection or manual entry) and outputs a numeric UV value, a color-coded risk category (Low to Extreme), the day's peak UV time and value, and a 3-hour forecast. The service also includes educational content on the WHO Global Solar UV Index and environmental factors that amplify UV exposure.
Key Features
- Live UV Index Display — Shows the current UV level with its numeric value and category (e.g., 0.9 Low), along with the day's peak value and time (e.g., 8.1 at 14:00).
- 3-Hour Forecast — Projects UV indices for the next three hours (e.g., 0.3 at 20:00, 0.1 at 21:00, 0.0 at 22:00) to help plan outdoor activities.
- Environmental Amplifier Information — Explains that water reflects up to 10% of UV, dry sand up to 15%, and fresh snow up to 80%, increasing effective exposure.
- Sun Protection Recommendations — Offers practical tips such as wearing a wide-brimmed hat, UV sunglasses, applying SPF 30+ sunscreen every 2 hours, and avoiding midday sun (11 AM–4 PM).
- UV Index Scale Reference — Displays the full WHO-defined scale (0–2 Low, 3–5 Moderate, 6–7 High, 8–10 Very High, 11+ Extreme) with corresponding actions.
- Current Weather Context — Provides temperature, humidity, cloud cover, and wind speed (e.g., 31.4°C, 54% humidity, 96% cloud, 16.1 km/h wind) alongside UV data.
Who is it for?
- Outdoor workers — Use the live UV and forecast to schedule breaks and apply sunscreen before peak exposure.
- Parents — Check the UV index to determine appropriate sun protection for children during outdoor play.
- Athletes and fitness enthusiasts — Monitor UV levels to time runs or swims to avoid high-exposure periods.
- Travelers — Quickly assess UV risk in unfamiliar environments, especially near reflective surfaces like water, sand, or snow.
What can you do with UV Index Today?
- Check real-time UV levels: Enter your location or allow auto-detection to see the current UV index, category, and peak value for the day.
- Review 3-hour UV forecast: Use the projected values to decide whether to postpone outdoor activities until UV drops.
- Learn about UV safety: Read the embedded educational content on UV radiation, the index scale, and how different surfaces affect exposure to make informed decisions.
FAQ
What does the UV index number mean?
The UV index ranges from 0 (Low) to 11+ (Extreme). A value of 0.9 is Low, meaning minimal protection needed. Categories determine recommended actions, such as seeking shade for values above 6.
How does the 3-hour forecast work?
The tool shows projected UV indices for the next three hours (e.g., 0.3 at 20:00, 0.1 at 21:00, 0.0 at 22:00) to help schedule outdoor activities.
The page explains that water reflects up to 10% of UV rays, dry sand up to 15%, and fresh snow up to 80%. This means UV exposure can be significantly higher near coasts or mountains.
