Every October list names the same warm-and-quiet places and calls it a price guide. This one is built on what the flight actually costs from London, then matched to the real October numbers: daytime highs, rainfall, and sea temperature where it matters. The trade-offs are stated plainly. The warmest picks cost more to reach, the cheapest is also the greyest, and fares move week to week, so we point you to a live search rather than quote a number that expires tomorrow.
What October gives you, sorted by fare
October splits two ways across these eight. For a last warm swim, head south: Malta and Crete still hold sea temperatures in the low 20s, but the flight costs more. For the cheapest city break, go east, where Krakow and Prague cost the least to reach and on the ground. In the middle sit Seville and Lisbon, warm enough to live outside with the summer crowds gone. The table below is the quick read, ranked cheapest to priciest for the flight from London.
| Destination | Typical fare from London | Daytime high | Rain | Sea temp | Watch out for |
|---|---|---|---|---|---|
| Krakow | €40 to €80 | ~14°C | 51mm | n/a | coolest and greyest |
| Prague | €40 to €80 | ~15°C | 34mm | n/a | short grey days |
| Budapest | €50 to €90 | ~16°C | 44mm | n/a | cooling fast |
| Porto | €60 to €100 | ~21°C | 158mm | n/a | wettest of the eight |
| Lisbon | €60 to €100 | ~22°C | 101mm | swimmable | around 11 wet days |
| Seville | €70 to €120 | ~26°C | 68mm | n/a | a wetter month than summer |
| Malta | €80 to €130 | ~25°C | 77mm | ~23°C | rain starts; festival crowds |
| Chania | €100 to €160 | ~23°C | 80mm | ~21°C | beach bars wind down late month |
Fare bands are typical shoulder-season ranges from low-cost carriers out of London, not live quotes. Check kiwi.com for the price on your dates.
The cheapest: Krakow and Prague
Krakow, cheapest to reach and on the ground

Krakow is the budget winner of the eight, with the cheapest food and drink by a clear margin, plus the Unsound experimental festival and autumn foliage in October. What you trade for it is warmth: around 14°C with the least sunshine of the list, so bring a proper coat and lean on covered sights when the grey settles in. From London Stansted or Luton the flight is about two and a half hours. Compare London to Krakow flights before booking.
A zapiekanka, a toasted baguette with toppings, at Plac Nowy in Kazimierz, with smoked oscypek cheese.
Prague, light festival and cheap beer

Prague’s Signal Festival, a free-to-walk light-and-video-mapping show across the historic buildings, usually runs in mid-October, and the autumn foliage peaks as summer crowds vanish. Days are short and grey, but this is one of the drier months at about 34mm. From London Stansted, Luton or Gatwick it is roughly two hours. Fares move, so scan London to Prague flights first.
Goulash with knedlíky, and a half-litre of Czech beer that stays defiantly cheap.
The mid-range: Budapest, Porto, and Lisbon
Budapest, thermal baths at peak season

Budapest lands its Autumn Festival arts programme and its peak thermal-bath season in the same month, while accommodation and flight prices slide after summer. Expect about 16°C by day and roughly seven wet days, so the outdoor ruin-bar evening now calls for a warm layer. From London Luton or Stansted the flight is two and a half to three hours. Check London to Budapest flights for your dates.
Warm chimney cake, kürtőskalács, from a market stall, and paprika-harvest dishes on every menu.
Porto, the best-in-idea, spoiled by rain
Porto’s numbers look ideal on paper: mild highs near 21°C and a real shoulder-season price drop from London. The problem is the biggest on this list, about 158mm of rain, the wettest of the eight. It rewards a flexible traveller and punishes a fixed sunny itinerary, so treat it as a maybe rather than a beach book. If you go, build the days around port tastings in Vila Nova de Gaia, which work whatever the sky does. Flights from Gatwick, Luton or Stansted run around two and a half hours. Compare London to Porto flights when you decide.
Francesinha, the beer-and-spicy-sauce-smothered sandwich, is the rainy-day lunch.
Lisbon, warm but pack for rain

Lisbon holds a genuine shoulder season in October, around 22°C with a sea still swimmable through much of the month, and the summer queues and peak prices ease off. Where it bites is the rain: roughly 100mm across about eleven wet days, more than its neighbours, so plan a few covered backups and you will not mind. From Heathrow, Gatwick, Stansted or Luton it is two and a half to three hours. See London to Lisbon flights for current fares.
Pastéis de nata in Belém, then a salted-cod, bacalhau, dinner.
The priciest to reach: Seville, Malta, and Chania
Seville, 26°C with the crowds gone

October is the peak of Seville’s post-summer warmth, around 26°C by day, and because it is now shoulder season the fierce heat and the spring-festival prices are both behind you. Two things to pack for: October is one of the wetter months, and evenings drop to about 15°C. From London Gatwick or Stansted the flight runs two and a half to three hours. Line up your dates against London to Seville flights .
Work the tapas trail: espinacas con garbanzos and salmorejo at El Rinconcillo, the oldest tavern in town.
Malta, the last proper beach month

Sliema and St Julian’s keep the budget stays and the dining, and the sea holds around 23°C in October, warm enough to swim. Valletta’s Notte Bianca festival fills the capital on one autumn night, so book around it. Be honest with yourself about the money: island bus and summer pricing tend to run on through October, so what you gain here is thinner crowds more than lower prices, and the first real rain arrives by month’s end. From London Gatwick or Stansted the flight is around three hours. When your dates are set, check London to Malta flights for the live price.
Order fresh lampuki, the local catch that is in season into autumn, in a tomato-and-caper sauce.
Chania, Crete, the warmest Greek pick
Chania wraps around an old Venetian harbour, and October brings the start of the island’s olive harvest, which means oil pressed the same week you taste it. The sea is still about 21°C. Two things to weigh: rain climbs through the month toward 80mm, and some beach bars, ferries and seasonal restaurants start winding down from mid-to-late October, so go earlier rather than later. From London Gatwick or Stansted it is roughly three and a half hours, and fewer off-season routes keep the fare higher than the rest. Prices shift, so compare London to Chania flights before you commit.
Try dakos, the Cretan barley-rusk salad, with a drizzle of that new oil.
How to make the call
Chasing a last swim, pick Malta or Chania and go before late October, and accept the higher fare. Want warm-and-cheap in balance, start with Seville, then Lisbon if you will trade some rain for a bigger city. Price above everything, Krakow first, then Prague. Nervous about rain, skip Porto, which is the spoiler here. Because these routes often involve a self-transfer between separate flights, it is worth knowing the Kiwi.com Guarantee protects the connection if a delay breaks it. Fares change week to week, so for the live price run a search for your exact dates on kiwi.com .
Frequently asked questions
Where is actually warm in Europe in October?
Malta and Crete are the pick, with sea temperatures around 21 to 23°C and daytime highs of 23 to 25°C. Seville is warm on land at about 26°C but not a swimming choice. The further north you go on this list, the more October becomes a city-break month than a beach one.
What is the cheapest European destination in October?
Krakow, by a clear margin on the flight and on the ground, with the cheapest food and drink of the eight. Prague follows, and both pair low costs with sub-three-hour flights from London. The trade is that both are the coolest and greyest picks here.
Should I avoid Porto in October?
If you are set on sun, yes, because it sees the most rain of any destination on this list at about 158mm. If you are flexible and happy to plan around port tastings and whatever the sky does, it is a genuinely affordable shoulder-season city break.
Do I need a swimsuit in October?
Only for Malta and Crete, where the sea is still warm enough for a real swim. Everywhere else on the list, October is a walking-and-café month, so you can leave the swimsuit at home.
