UV index in Rome right now

Very high UV

The next daylight peak in Rome is forecast at UV 8.4 around 13:00 — the very high band. Type II skin would have about 20 min at that level. No level is risk-free — this is when to come in, not how long you may stay.

The sun in Rome

Rome sits inland at 41°N, without the sea breeze that softens coastal heat — the sun here is felt as well as taken. The exposure pattern is the tourist day itself: the Forum, the Palatine and the queues around the Vatican and the Colosseum are long stretches of open ground where visitors stand still in full sun through the middle of the day.

From May to September the midday index reaches the high band, and the city’s rhythm works against visitors: the major sites are busiest exactly when the sun is strongest. The classic mistake is treating a sightseeing day differently from a beach day — three hours of slow walking between ruins at midday is a beach-level dose, taken without a towel to retreat to.

Time to first redness at tomorrow’s peak (UV 8.4), by skin type

Estimated minutes of unprotected sun before the first redness, at UV 8.4. An estimate, not a safe allowance — skin damage builds up before any redness shows. Below 20 minutes is in red.
Skin type	Before first redness
I — Always burns, never tans.	16 min
II — Burns easily, tans minimally.	20 min
III — Burns moderately, tans gradually.	24 min
IV — Burns rarely, tans easily.	32 min
V — Burns very rarely, tans very easily.	40 min
VI — Almost never burns, always tans.	48 min

Rome — the questions people actually ask

What is the UV index in Rome right now?

This page reads the MET Norway forecast for Rome and refreshes every 15 minutes. The chart above shows the next daylight hours hour by hour; the answer changes through the day, which is why it is measured rather than written down.

When do you need sun protection in Rome tomorrow?

The WHO recommends sun protection from UV 3 upward, for every skin type. On the current forecast, Rome is at or above UV 3 from 09:24–16:50 local time tomorrow. Outside that span the index is lower — the dose still accumulates, just more slowly.

Can you tan in Rome tomorrow?

The forecast peak is about UV 8.4 at 13:00, above the roughly UV 2 threshold where melanin production starts — so the skin will respond. That response is damage: there is no risk-free tan at any level. What this page gives you is the other number — about 20 min before first redness for type II at the peak — as a point to stay well under, not a target.
