12 European Cities That Are Better in October

Lisbon in October is what Lisbon in August is pretending to be. The heat has broken, the days sit in the low twenties, and the light across the river in the late afternoon is the reason painters stayed. The summer crowds on the trams have gone home, so you can ride up to the viewpoints without standing in a queue. Walk the hills in the morning, take a ferry across the Tagus for lunch, and eat grilled fish outside without a fan pointed at you. The sea at the nearby beaches is still warm enough for the brave.

Harvest in the Douro Valley runs into October, and Porto is where the wine comes down the river to rest. The city is cooler and greener than Lisbon, with a mist that lifts off the water in the mornings and a riverfront best walked without summer's crowds. October brings the first proper rain, which suits a place built around cellars, bookshops and long lunches. Take the train up the valley for a day among the terraced vines, then come back for a glass of something young and a plate of whatever the kitchen has.

Seville in July is a test of character. Seville in October is one of the most pleasant cities in Europe. The temperature drops from the high thirties to the mid-twenties, the evenings are warm enough to sit outside until midnight, and the orange trees are heavy with fruit you are not supposed to eat. Spend the afternoon in the shaded gardens, then do what the city does: eat small plates standing at a bar, move to the next one, and let dinner last until one in the morning.

Romans have a word for their October: the ottobrate, the warm, golden days between the summer heat and the winter rain. The city is still busy, because Rome always is, but the August crush has gone and the light on the stone in the late afternoon is at its best. Walk early, eat late, and give the famous sights a miss in favor of the neighborhoods across the river. October is also artichoke and porcini season, which the trattorias take seriously. Sit outside and order what is written on the board, not the menu.

Florence in summer belongs to the tour groups. In October it starts to belong to itself again. The queues shorten, the river turns the color of the hills, and the hills themselves are in harvest, with the olives coming in and the new oil arriving in the restaurants by the end of the month. Have one museum morning, then leave the center for the gardens above the city and a long lunch with a view. The evenings are cool enough for a jacket and warm enough to walk home along the water.

Athens has two good seasons and October is the better one. The heat that makes the city hard work in July has lifted, the sea is still warm from summer, and you can climb the hill above the city in the afternoon without wilting. The islands are winding down, so the ferries are quiet and the city feels like it has exhaled. Spend the day in the markets and the neighborhoods below the rock, then take the tram to the coast for a swim and a fish dinner as the sun goes down.

In summer the old town can feel like a corridor. By October the cruise ships thin out, the day-trippers go, and the walls become a place to walk rather than a place to shuffle. The Adriatic is at its clearest and still warm enough to swim from the rocks below the walls. Prices drop sharply from their summer peak. Take the cable car up for the view at sunset, then eat in a courtyard with the stone still giving back the day's heat.

Malta's sea is at its warmest in October, having soaked up the entire summer, and the air has cooled enough to make the honey-colored streets of the capital a pleasure rather than an ordeal. Valletta is small, dense and built on a grid that drops steeply to the harbors on either side, so every street ends in a view of water. Swim in the morning, walk in the afternoon, and take the ferry across the Grand Harbour at dusk when the stone turns gold. It is one of the few places in Europe where an October beach day is a safe bet.

Paris empties in August and fills with visitors in September. October is when it settles. The chestnut trees turn along the river, the cafe terraces put out their heaters, and the city does what it does best: lets you walk for hours and sit for longer. The light is lower and kinder, the museums are quieter, and the food turns toward autumn, with game and mushrooms on the boards. Bring a coat, skip the big-ticket queues, and spend an afternoon in one park and one bookshop.

Vienna is a city built for autumn. The concert season is in full swing, the coffee houses come into their own as the evenings draw in, and the vineyards on the city's edge are pouring this year's young wine in taverns with gardens under the trees. The parks turn gold through October and the summer humidity is gone. Walk the Ring in the morning, take a tram out to the wine villages in the afternoon, and dress for a concert in the evening. Nobody will mind if you do not know the piece.

Prague's problem is that everyone knows about it. Its solution is October. The summer crowds on the bridge are gone, the mornings are misty enough to make the spires look like a painting, and the trees along the river and in the parks above the castle turn in waves through the month. It is cold enough for a coat and warm enough to walk all day. Cross the river early, climb to the gardens, and finish the afternoon in a pub with a stove and a beer that costs less than a coffee at home.

Budapest closes the list because October is the city at its best, and because the thermal baths are the point of the season. The outdoor pools steam in the cooling air, the trees on the hills across the river turn copper and gold, and the summer heat that makes the flat side of the city sticky has gone. Evenings are crisp enough for a long dinner indoors and warm enough for a walk along the embankment afterward. Soak in the morning, walk the hills in the afternoon, and watch the lights come on along the river. That is October done properly.
