Honestly, if you're looking at the Athens greece 14 day weather forecast right now, you’re probably seeing a lot of "cloudy with a chance of rain" and wondering if you should’ve just booked a flight to the Caribbean instead.
But here is the thing about Athens in mid-January. It isn't the frozen tundra people imagine northern Europe to be. It’s more like a moody, Mediterranean spring that can’t quite decide if it wants to be cozy or crisp.
Right now, as we move through the middle of the month, the city is settling into its coldest stretch. Today, Sunday, January 18, we're looking at a high of 47°F. That’s definitely "wear a real jacket" territory. Tonight, it'll dip down to 41°F with some light rain.

Basically, the next few days are going to be a bit of a damp squib if you were hoping for Vitamin D. Monday and Tuesday keep that trend going with highs struggling to break 50°F and a decent 75% chance of rain coming in Tuesday night.
The Mid-Week Washout and Why It Matters
If you are planning to trek up to the Acropolis on Wednesday, January 21, maybe... don't. The forecast is calling for a 90% chance of rain with a high of 55°F.
The marble on the Parthenon gets incredibly slick when it’s wet. I’ve seen enough tourists do the "Bambi on ice" routine to know that heavy rain and ancient ruins are a bad mix. Plus, the wind is kicking up from the northeast at about 11 mph, which makes that 55°F feel a lot more biting than it looks on paper.
Wait for Thursday or Friday.
The skies start to clear up toward the end of the week. Friday, January 23, is looking much better with "partly sunny" conditions and a high of 57°F. That is the Athens people actually come for—crisp air, blue-ish skies, and the kind of light that makes the Plaka look like a postcard even in the dead of winter.
What to Actually Pack (Forget the Shorts)
Look, I know you want to believe it’s always sunny in Greece. It isn't.
If you’re here for the next 14 days, you need layers. Not "T-shirt and a light cardigan" layers, but "thermal undershirt and a waterproof parka" layers. The humidity is sitting around 70-80% most days, which means the cold has a way of seeping into your bones if you aren't careful.
- Shoes with grip: I cannot stress this enough. Cobblestones + rain = disaster. Leave the stylish flat-soled boots at home.
- A real scarf: The wind tunnels between the city buildings can be brutal.
- The "Double P": Parka and Pants. You won't see a single local in shorts right now, and you shouldn't be the exception.
By next weekend, January 25, things actually warm up a bit. We’re talking a high of 61°F. It’s a weirdly warm spike before the rain returns on Monday. That is the Mediterranean for you—it’s volatile.
The "Alkyonides" Myth vs. Reality
You might hear locals talk about the "Halcyon Days"—a mythical period in late January where the sun comes out and it feels like summer for a week.
Don't bet your vacation on it.
While we do get those sunny breaks, the current Athens greece 14 day weather forecast suggests more of a "mixed bag" scenario. You’ll get 4 or 5 hours of sunshine on a good day, but the sun sets early, around 5:30 PM. Once that sun goes down, the temperature drops fast.
The upside? No crowds.

You can stand in front of the Temple of Hephaestus and be the only person there. You can get a table at that cozy taverna in Psirri without a reservation. Just bring an umbrella for the walk there.
Your Action Plan for the Next Two Weeks
If you’re on the ground in Athens or arriving soon, here is how to play it:
- Museum Days: Save the National Archaeological Museum or the Acropolis Museum for Wednesday (the 21st). It’s going to be a washout, so stay inside and look at gold masks.
- Outdoor Sights: Aim for Friday, Jan 23, or Tuesday, Jan 27. These are the "partly sunny" windows where you won't get drenched.
- Nightlife: Stick to the indoor bars in Exarcheia. The outdoor seating with space heaters is great, but when that northeast wind hits 12 mph, even the heaters give up.
Check the sky every morning. The clouds move fast over the Saronic Gulf, and a "cloudy" forecast can often turn into a stunning sunset if the wind shifts west.
Keep your layers handy, keep your expectations realistic, and honestly, enjoy the rain. There is something incredibly atmospheric about seeing the ancient columns of the Olympieion against a dark, stormy sky that the summer tourists never get to see.
To stay prepared, make sure to check the daily updates for any shifts in wind direction, as a move from northeast to southwest usually signals a quick rise in temperature.
