Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.
The numbers
| Daily high | 24°C |
|---|---|
| Nightly low | 17°C |
| Feels like, afternoon | 25°C |
| Rainy days, 1 mm or more | 10 · 198 mm |
| Humidity | 68% |
| Sunshine | 10.0 h/day |
| Daylight | 12.5 h/day |
| Crowds | 65 / 100, higher is quieter |
Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.
Weather read at Piazza Unità d'Italia, 31 km from the airport (TRS): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

What to pack
- A packable rain jacket for the 10 or so rainy days.
- Sun protection: about 10 hours of sunshine a day.
Each line is a threshold over the ten-year figures above, not advice from anywhere else.
