SunticUV index in Miami today
Miami's subtropical climate means strong sun for much of the year, not just in high summer. The only accurate figure is a live one for your exact spot: Suntic shows Miami's real-time UV index and a 10-day forecast.
Sun and UV in Miami
Sitting at a low latitude on the Atlantic coast, Miami gets intense sunshine across a long season. Midday UV regularly climbs into the very high range from spring through autumn, and even winter days can reach moderate-to-high levels. Afternoon thunderstorms are common in summer, but the clouds roll in late and rarely block the strong morning and midday UV.
When is UV highest in Miami?
UV is highest around solar noon (broadly 10am to 4pm) and strongest across March to September. The exact peak shifts with the season and the day's weather. For more on this, see when is the sun strongest.
The UV index scale
| UV index | Risk level | What to do |
|---|---|---|
| 0-2 | Low | Minimal risk. Safe to be outside; sunglasses on bright days. |
| 3-5 | Moderate | Take care at midday. Use SPF 30+, a hat and shade around noon. |
| 6-7 | High | Protection needed. SPF 30+, cover up, seek shade 10am-4pm. |
| 8-10 | Very high | Extra protection. Avoid the sun at midday; SPF, clothing and shade are essential. |
| 11+ | Extreme | Take all precautions. Unprotected skin can burn quickly; stay inside or fully covered at peak hours. |
UV index categories follow the World Health Organization / US EPA scale.
Staying sun-safe in Miami
- Sand and the ocean reflect UV back up at you on the beach, so you get more exposure than the index alone suggests.
- Humidity and a sea breeze make the heat feel manageable while the UV stays high, so go by the index, not how warm it feels.
- Shade from a palm or umbrella helps but doesn't block reflected and scattered UV, so keep sunscreen on.
Wherever you are, the basics hold: use broad-spectrum SPF 30+, seek shade around midday, cover up, and never let your skin burn. See our sunburn prevention tips.
