Lisbon’s climate in brief
Lisbon has a Mediterranean-style climate with long, dry summers and mild, damp winters. Sunshine is plentiful for much of the year, which is a big part of the city’s appeal. The Atlantic keeps evenings breezier than you might expect, so a light layer is useful even in warm months. Weather is never guaranteed, so use the figures below as general guidance and check a forecast before you pack.
Month-by-month guide
| Season | Feel | Crowds and prices |
|---|---|---|
| December to February | Mild, with the most rain of the year | Quiet, cheaper stays, Christmas and New Year peak briefly |
| March to May | Warming up, longer days, some showers early on | Rising steadily, busier at Easter |
| June to August | Hot and dry, strong sun | Highest demand, festivals in June, expensive flights in school holidays |
| September to November | Warm early, cooler and wetter later | Good value in September and October, quieter by November |
The best months for most travellers
April to June
Spring brings comfortable sightseeing weather, blossoming trees and long evenings. June is lively thanks to the Santos Populares festivals, when neighbourhoods fill with street parties, grilled sardines and decorated streets. Expect more visitors and higher prices around the busiest festival days, so book early if those dates matter to you.
September and October
Early autumn is a favourite with locals and repeat visitors. The heat of high summer fades, crowds thin, and flights often fall compared with July and August. It is a strong choice if you want to walk the hilly streets without struggling in the afternoon sun.
When to go for specific goals
- Cheapest trip: aim for the winter months outside the holidays, or the weeks either side of peak summer.
- Beach days: late spring to early autumn. The Atlantic is cool even in summer, so expect refreshing rather than warm water.
- City walking and photography: April to early June and late September to October.
- Fewest crowds: January and February, accepting a higher chance of rain.
Flight tips for Lisbon
Lisbon airport (LIS) is one of Europe’s busier hubs and is connected to the city by the metro’s red line, which makes arrival easy and cheap. Because so many airlines fly in, comparing the whole market is worth the few minutes it takes. Our guide to cheap flights to Lisbon covers fares in more depth.
A few habits help keep costs down: search flexible dates, check midweek departures, compare bag and seat charges across airlines, and set a price alert if your dates are more than a month away. For summer and school holidays, start looking earlier than you would for a quiet month.
What to pack
Comfortable, grippy shoes matter most. Lisbon’s streets are steep and many pavements are polished stone that becomes slippery after rain. Add sunscreen, a hat and a refillable bottle in summer, and a light waterproof in winter and shoulder seasons. A carry-on-only trip works well here and means you can go straight from the airport to the metro. See our packing light checklist for ideas.
Combining Lisbon with other places
Many visitors add a day trip to Sintra or the coast, or travel north to Porto by train. If you are planning that kind of route, consider an open-jaw ticket that lands in one city and departs from another, which avoids doubling back. Compare it against a standard return before you book.
Check entry and passport requirements for your nationality ahead of travel, using official government sources, as rules can change.
