The sun in Split

Split faces the Adriatic at 43°N, and its exposure is as much on the water as in the streets: ferry decks to the islands, boat trips, and the Riva promenade offer long hours in direct sun with the sea adding reflected light from below. The white Dalmatian stone of the old town does the same in the streets.

The Adriatic summer is remarkably cloudless — from June to early September clear-sky days follow each other for weeks, so the forecast rarely rescues anyone. The classic trap is the boat day: wind and spray keep skin cool on deck while the combination of open sky and water reflection pushes the dose above what the same hours would deliver on land.

Split — the questions people actually ask

What is the UV index in Split right now?

This page reads the MET Norway forecast for Split 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 Split tomorrow?

The WHO recommends sun protection from UV 3 upward, for every skin type. On the current forecast, Split is at or above UV 3 from 09:12–16:26 local time tomorrow. Outside that span the index is lower — the dose still accumulates, just more slowly.

Can you tan in Split tomorrow?

The forecast peak is about UV 7.9 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 21 min before first redness for type II at the peak — as a point to stay well under, not a target.
