SunGlow Guide
Not all hours of sunlight are created equal. Here's when to tan for maximum results with minimum burn risk, broken down hour by hour.
The UV index follows a predictable curve each day, rising from sunrise, peaking around solar noon (typically 12-1 PM), and declining through the afternoon until sunset. But here's what most people miss: the shape and height of that curve changes dramatically with the season, your latitude, and local weather. In summer, UV can spike to 8-10+ at midday, making even short exposure risky for fair skin. In winter or at higher latitudes, the peak might only reach 3-4. Knowing where you are on this curve at any given moment is the single most important factor in safe tanning. Tan during the wrong hour and you burn. Tan during the right hour and you build color gradually with far less risk.
Every article about tanning time gives you the same advice: avoid 10 AM to 2 PM. But that's a one-size-fits-all rule that ignores where you live, the season, cloud cover, and your skin type. In Seattle in March, the UV at noon might be 3 — perfectly safe for moderate sessions. In Miami in July, UV 7 can hit as early as 9 AM, making even the 'safe' morning hours risky. SunGlow shows you the actual UV index right now at your location, not a generic rule from a dermatology pamphlet. Check the app, see the real number, and make an informed decision about whether this is a good tanning hour for you specifically.
Open SunGlow and look at the current UV index and the hourly forecast. This tells you whether now is a good time to tan and how long you have before UV gets too intense or drops too low.
For gentle base-tan building, aim for UV 3-5 (typically early morning or late afternoon in summer). For faster results with careful monitoring, UV 5-7 works if you keep sessions short. Avoid UV 8+ unless you have darker skin and extensive tanning experience.
If you're a beginner, schedule your sessions for the rising UV (morning) or declining UV (afternoon) sides of the curve rather than the peak. You'll get more consistent, controlled exposure with less burn risk.
UV can change during your session, especially if clouds move in or out. SunGlow tracks this in real time so you know if conditions have shifted since you started. If UV spikes unexpectedly, the app will let you know.
Instead of memorizing generic tanning schedules, let SunGlow show you the real-time UV at your location. The app displays the current UV index, helps you calculate your safe exposure window, and times your session with relaxing lo-fi music. Whether you're tanning at home, on vacation, or at altitude, SunGlow gives you the data you need to choose the right hour every time.
Yes, especially in summer when UV rises quickly. UV 3-5 in the morning hours provides great tanning conditions with lower burn risk. Check SunGlow for the exact UV at your location and time.
Neither is inherently better. What matters is the UV index at that specific hour on that specific day. Morning and late afternoon typically offer moderate UV levels ideal for controlled tanning. SunGlow removes the guesswork by showing you the actual number.
Absolutely. In winter at northern latitudes, the UV index may never exceed 2-3 even at peak hours. This means longer sessions are needed for any tanning effect, and the window of useful UV is much shorter. SunGlow adjusts for seasonal changes automatically.
