Italy’s Cool Summer Towns, 2026 Update: Where To Live And Beat The Heat

A year on, we re-ran our feels-like summer analysis across all 7,896 Italian comuni. In light of constantly rising temperatures, we have moved the comfort line up and listed out all the Italian towns where you can hope to spend summer without the sweltering heat. Here is what the new data shows, and a new way to filter it.

The coolcation trend did not cool off

When we first mapped Italy’s cooler corners in 2025, the “coolcation” trend was still half travel-supplement novelty, half real estate sales gimmick. It is neither now. It is a structural shift in how people plan a new life in Italy.

Trip.com’s 2026 booking data shows searches for cooler, less crowded destinations up about 74 percent year on year. Iceland, the Nordics and the Baltics are, for a growing share of travelers, the main choice of destination. Forecasters expect 2026 to land among the hottest years on record, and the heat is doing the marketing. When Rome and Madrid bake, the search bar fills with milder places.

And it is certainly not just a matter of holidays. It is a relocation and second-home question. The people reading this are not booking a long weekend in Reykjavik. They are asking whether the Italian town they love will still be comfortable in August twenty years from now. That question finds an answer in our data.

Why we re-ran the numbers

Two things changed since our first analysis:

• Wherever you sit on the causes of the whole climate change debate, Italy is hotter. A summer afternoon that felt like 26 degrees two decades ago would have been normal. But is not the baseline any more. Holding the old comfort threshold fixed would have shrunk the list of cool towns every summer. We have adjusted our maximum feel-like temperature requirements to reflect this.
• Second, we rebuilt the dataset from the ground up. The new analysis runs on Open-Meteo reanalysis covering 2010 to 2019, daytime values, across every one of Italy’s 7,896 comuni. For each town we have the June, July and August apparent temperature and relative humidity, which lets us work in “feels-like” terms rather than raw thermometer readings.

Apparent temperature is the right word for this: this metric folds humidity, wind and sun into a single number that tracks what a body actually feels. A dry hill town at 27 degrees can feel pleasant. A humid lakeside at the same 27 degrees can feel oppressive. Raw air temperature hides that difference.

Our new comfort line: 27 degrees

Here is the headline change. We moved the temperature comfort line up to a June-to-August mean apparent temperature of 27 degrees or below. That is a deliberate, slightly generous threshold, and it reflects the warming baseline rather than ignoring it. On this basis, 3,418 comuni qualify as coolcation towns. That is roughly 43 percent of Italy.

A bigger number is not a softer one. It is a more honest one, because it lets the reader decide where their own comfort line sits rather than having us decide for everyone. Plenty of people are perfectly happy with a warm-but-not-brutal 27 degree afternoon and an aperitivo in the shade. Plenty of others want genuine mountain freshness. The same dataset serves both, which brings us to the real upgrade.

Six summer heat bands

The most useful new feature is not the flag. It is the scale behind it. Every town now sits within a single summer heat band, from coldest to hottest, built from that same June-to-August feels-like average.

• Alpine, 18 degrees or below. 67 towns. The genuine high-mountain refuges, where a sweater earns its place on a July evening. Think Sestriere or Livigno, sitting around 14 to 15 degrees.
• Cool, 19 to 22 degrees. 331 towns. Classic mountain-resort and spa-town territory. Courmayeur, Bormio and Vipiteno live here.
• Mild, 23 to 25 degrees. 1,009 towns. The sweet spot for most people. Warm enough to feel like an Italian summer, gentle enough to sleep without air conditioning. Agerola, Monte Sant'Angelo and Fonni sit in this band.
• Warm, 26 to 27 degrees. 2,011 towns. Comfortable rather than cool, and still inside the coolcation line. Campobasso and Gangi land here.
• Hot, 28 to 29 degrees. 3,088 towns. The most common summer in Italy, and the point where the coolcation flag switches off.
• Sweltering, 30 degrees or above. 1,390 towns. The lowland and southern coastal heat that the whole trend is running away from. If you decide to live here, air conditioning is all but necessary.

If you want only the genuinely cool places, filter on the Explorateur de villes to Mild and below and you are down to 1,407 towns. Want true mountain air? Cool and Alpine together are just 398. We are giving you more flexibility than a mere “This town feels cool in the summer” button.

What surprised us: the humidity catch

Here is the finding that separates this analysis from the Instagram versions of the story “Italy is hot”.

Reputation said Lake Garda and the Ligurian coast near Sanremo were cool-weather spots. The feels-like data disagrees. Malcesine on Garda and Sanremo both come out at about 29 degrees, squarely in the Hot band, outside the coolcation line.

The reason is humidity. Water moderates air temperature, so the thermometer reading looks moderate. But that same water loads the air with moisture, and high humidity pushes the feels-like figure up, not down. Measured by what a body actually feels on a July afternoon, a humid lakeshore or coast can sit warmer than a dry hill town that shows a higher number on the thermometer.

This is exactly why we work in apparent temperature. The lazy coolcation list leans on lakes and coastlines because they sound refreshing. The honest one sends you uphill and inland, where the air is drier and the evenings actually cool down.

Ten towns for a cooler summer, north to south

These ten towns summarise the story, now with their updated feels-like values and bands from the new dataset. They range from alpine resorts to southern hilltop borghi, and every one stays at or below the comfort line.

Climate comfort is now a property factor

From the Alps to the islands, these towns point at a bigger shift. Climate comfort has become a real ingredient in where people buy, not just where they holiday.

Mountain and hill-town property, once written off as too remote, reads differently when the alternative is a coast that hits 40 degrees and a house that needs air conditioning to be liveable in August. A breezy borgo at 700 metres starts to look less like a compromise and more like a hedge. Buyers are beginning to price that in, and local administrations in cooler areas have noticed the opportunity.

The European Environment Agency’s long-range projections sharpen the point. Under harsher warming scenarios, parts of Southern Europe face steep declines in farmland value by 2100, with Italy carrying a large share. Today’s hottest property markets are not guaranteed to stay the most desirable ones. Climate resilience is becoming part of the Italian dream, alongside the view and the espresso.

None of this means abandoning the Amalfi Coast for the Dolomites. It means the alternatives are real, they are mapped, and more people are choosing them on purpose.

Find your own comfort line

The whole point of the new band system is that “cool” is personal. One person’s pleasant 27 degrees is another’s too-warm. So rather than hand you a single list, we built a scale you can set yourself.

Use the Explorateur de villes to filter by summer heat band, elevation and more. Want a medieval borgo that stays Mild or below all summer? Filter to it. Want true Alpine air and snow in winter? That is two clicks. The climate is changing, but with the right data, buyers and travellers can change with it, and keep their cool in every sense.

Method and sources

Data: Open-Meteo reanalysis, 2010 to 2019, daytime averages, all 7,896 Italian comuni.

Coolcation flag is a June-to-August mean apparent temperature of 27 degrees or below. Summer heat band is derived from the same June-to-August mean: Alpine 18 or below, Cool 19 to 22, Mild 23 to 25, Warm 26 to 27, Hot 28 to 29, Sweltering 30 or above. Town feels-like figures are rounded to the nearest degree.

Trend figures are drawn from 2026 travel industry reporting, including Trip.com booking data on the rise in searches for cooler destinations.

Climate and land-value projections for Southern Europe come from European Environment Agency studies.
