Rain days are the days with at least 1 mm of rain, as a weather station counts them.

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.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest from June to September; quietest from November to March.

Then and now

Trieste's June days now average 27.2°C, 4.4°C warmer than in 1981–1990. 11 of 12 months are clearly warmer.

Getting there

How far Trieste is, and what it costs, depends on where you set off from — the months above do not.

Before you go

Type C and F and L plugs at 230 V. Drives on the right. The currency is the Euro. No UK Foreign Office advice against travel. Everything for Italy: cost of living, languages, emergency numbers and health.

Being there

On arrival

Paying — By law, shops, cafés and bars must take a card payment of any amount, and refusing one is fined. Carry a little cash for tips.
UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
Tipping — Not customary; restaurants outside Rome often add a cover charge (coperto). Leaving the change in cafés and taxis is common.

Getting around Trieste

Tap a contactless Mastercard, Visa or American Express card, or a phone, on the Eva validator each time you board a bus or the Opicina tram, and at the end of the day you are charged the best fare (60 minutes, 75 minutes or the day). Paper tickets from ticket offices, retailers and machines cost €1.50 for 60 minutes, €1.85 for 75 minutes and €3.35 for the day; scan the QR code on Eva as you board. From Trieste Airport, a walkway leads to its own station on the Trieste–Venice railway, and APT buses to Trieste leave from the bus station beside it.

Apps — Rides: FreeNow, itTaxi, Uber. Maps: Google Maps, Apple Maps. Messages: WhatsApp. In Rome these apps book licensed taxis; Uber also offers the dearer Uber Black.

Like most of Europe, a stroll through the town to admire its ancient architecture is a very popular activity. You get to travel at your own pace and even get some coffee along the way. More on Wikivoyage
