So you're looking at the 14 day forecast Lisbon and thinking about packing a swimsuit. Honestly, I get it. Lisbon has this reputation for being the "Sun-Kissed Capital" where winter doesn't really exist. But if you’re heading there in late January 2026, you need a bit of a reality check. It isn't exactly the North Pole, but it’s not the Algarve in August either.
Right now, the city is sitting at a cool 48°F (about 9°C) as we head into the night of January 18th. There’s a light north wind at 6 mph, and the humidity is hanging heavy at 77%. If you’re standing on a terrace in Alfama tonight, it’s going to feel more like 45°F.

Basically, it's "bring a jacket" weather.
The Two-Week Outlook: Rain and Refracted Light
The next 14 days in Lisbon are going to be a bit of a rollercoaster. We’ve got a mix of crisp, sunny mornings and those sudden Atlantic downpours that turn the city's famous calçada (stone pavement) into a literal ice rink. Seriously, wear shoes with grip.
- Monday, January 19: Expect a high of 57°F and a low of 47°F. It’ll be partly sunny, but that north wind is picking up to 11 mph.
- Tuesday, January 20: The clouds move in deep. We’re looking at a 70% chance of rain by nightfall, with temps steady around 57°F.
- Wednesday, January 21: This looks like the wettest day of the week. Heavy light rain (if that's a thing) with a 40% chance during the day and a high of 61°F. It’s warmer, but damp.
- The Late-January Clearance: After a soggy stretch through Friday the 23rd, things start to dry out. By Tuesday, January 27, we’re looking at mostly sunny skies and a very comfortable 59°F.
The big thing people miss is the humidity. 88% humidity on a 60-degree day feels a lot different than 60 degrees in a dry climate. It gets into your bones.
Why Winter Lisbon is Actually Better
If you can handle a little bit of rain, this is the best time to see the city. You’ve probably seen those TikToks of people waiting three hours to ride the Number 28 tram. In January? You can basically walk right on.

The light is different too. Photographers love this time of year because the sun stays lower in the sky, casting these long, dramatic shadows against the yellow buildings. When the sun hits the wet tiles after a shower, the whole city glows. It’s kinda magical, actually.
The hills of Lisbon are no joke. Walking up to the Castelo de São Jorge in 90-degree heat is a special kind of misery. Doing it in 55°F weather? That’s just a pleasant stroll.
What to Actually Pack (The Non-Bikini List)
Forget the "Mediterranean summer" vibe for a second. Lisbon houses are notoriously bad at keeping heat in. Most of those charming Airbnbs you see don't have central heating. They might have a little space heater, but you’ll want a solid pair of wool socks for lounging around the room.
- Waterproof boots with traction: I cannot stress this enough. The limestone stones are beautiful but treacherous when wet.
- Layers: A light down jacket or a trench coat over a sweater is the way to go.
- A sturdy umbrella: The wind off the Tagus River will snap those cheap $5 umbrellas in seconds.
The Forecast vs. The Feeling
Temperature-wise, Lisbon is one of the warmest capitals in Europe during winter. While London is shivering at 35°F, Lisbon is lounging at 58°F. But the "feels like" factor is huge.
The wind is currently coming from the north, which brings a bit of a bite. Later in the week, it shifts to the west. That's the Atlantic wind. It brings the rain, but it also brings milder air. Wednesday the 21st will actually be the warmest day of the week at 61°F, even if you need an umbrella to enjoy it.
Your Lisbon Winter Strategy
Don't let the 14 day forecast Lisbon scare you off. Just pivot your plans.
If the forecast shows rain for the afternoon, that’s your cue to head to the Museu Calouste Gulbenkian or the Oceanário. Save the rooftop bars for the 26th and 27th, when the sky clears up and the UV index bumps up to a whopping... 2. Hey, it's better than zero.
Actionable Next Steps:
- Check the wind direction: North wind means "extra scarf," West wind means "carry the umbrella."
- Book a fado dinner for the rainy nights: Nothing beats the "saudade" of a rainy Lisbon night like some soul-crushing Portuguese blues and a glass of red wine.
- Look for accommodation with "Ar Condicionado" (AC): Most units in Lisbon double as heaters. You'll thank me when it's 44°F outside at 3:00 AM.
