Frequently Asked Questions
Is the UV index on this website accurate?
In general, yes. Our UV index data comes from professional meteorological services that use satellite observations and ground-based measurements. However, since the UV index is forecasted using time series models, there may be some bias or deviation from actual measured values, especially during rapidly changing weather conditions.
How often is the UV index data updated on this website?
The UV index data is updated hourly to reflect current conditions. Our system retrieves the latest hourly forecast data from meteorological services, ensuring you always see the most current UV index for your location. The displayed time stamp shows when the current reading was recorded.
How does this website detect my location?
We automatically detect your approximate location based on your IP address using geographic data services. This allows us to show you the UV index for your area without requiring you to manually enter your location. The location detection is automatic and happens when you visit the website.
Does this website store my personal information or location data?
No. We do not store any personal information or location data. Location detection is performed automatically based on your IP address, but we do not save, track, or store this information. Weather data is cached temporarily (up to 2 days) to improve performance, but this does not include any personal identifiers.
Is this website free to use?
Yes, this website is completely free to use. There are no registration requirements, subscription fees, or hidden costs. You can access all UV index data, forecasts, and guides without any charges.
What regions or countries does this website support?
This website provides UV index data for locations worldwide. We use global meteorological services that cover virtually all countries and regions. If you are using a VPN or proxy, the location detection may show a different location than your actual one.
What information does the website display besides the UV index?
In addition to the current UV index, we display the maximum UV index for today, the time when UV peaks, current temperature, maximum temperature, cloud cover percentage, humidity, wind speed, and a 3-hour UV forecast. We also provide risk descriptions and sun protection recommendations based on the UV level.
Why might the displayed location be inaccurate?
Location accuracy depends on your IP address geolocation data. If you're using a VPN, proxy server, or corporate network, the detected location may reflect the location of your network's exit point rather than your physical location. Mobile networks and some ISPs may also route traffic through different geographic locations.
Does this website provide historical UV index data?
Currently, we focus on providing current and forecasted UV index data. We do not maintain historical archives or past UV index records. The website is designed to help you make real-time decisions about sun protection.
