How to Check the UV Index Where You Live (Free EPA Tools)
The EPA's free SunWise app gives location-based daily and hourly UV forecasts — plus ZIP-code lookups, a 4-day map, and email UV Alerts to plan your day.
The EPA's free SunWise app provides location-based daily and hourly UV Index forecasts in English and Spanish, and the EPA also offers UV Index lookups by ZIP code, a 4-day national map, and email UV Alerts via EnviroFlash.
The EPA promotes these free tools as a way to make sun-safe planning routine, recommending people check the UV forecast the way they'd check the weather so they can time outdoor activities and protection around the strongest UV hours.
Questions we get a lot
What is the EPA SunWise app?
SunWise is a free EPA app that provides location-based daily and hourly UV Index forecasts, available in both English and Spanish. It lets you see when UV will peak in your area so you can plan protection accordingly. Because it's tied to your location, it gives a more relevant forecast than a generic number.
How can I get the UV Index for my ZIP code?
Beyond the SunWise app, the EPA offers a UV Index lookup by ZIP code along with a 4-day national UV Index map. These let you check conditions for a specific location and see broader regional trends. They're free public tools available through the EPA.
Can I get UV alerts sent to me automatically?
Yes. The EPA's EnviroFlash service can email you UV Alerts so you're notified when high UV is expected, without having to remember to check. Combined with the SunWise app's forecasts, it makes building sun protection into your day much easier. All of these resources are free.
