Stockholm in the fall feels like a clear shift from lingering summer warmth to the chill of winter. You’ll see average highs drop from the mid-60s °F (around 18°C) in early September to the upper 30s °F (about 3°C) by late November. Nights cool off fast, often flirting with freezing as the season rolls on.
Clouds start piling up, and daylight slips away at a surprising pace. The city feels different every month. Rain sticks around, but as things get colder, you start to see a mix of rain and light snow by November. Winds get a little stronger, cranking up the chill, and the nearby water loses its warmth quickly, hinting that winter’s not far off.
These changes shape how you dress and what you do outside. Want to catch those last crisp September walks? Or maybe you’re bracing for dark October afternoons or hoping for the first snowflakes. Knowing what’s coming helps you make the most of Stockholm’s fall weather.

Humidity and Wind Conditions
During fall, Stockholm’s air feels pretty damp, and breezes off the water can make things feel cooler than what the thermometer says. Moisture stays high, and steady winds make a difference, especially near the waterfront or in open spaces.
Average Humidity Levels
Humidity stays high through the fall. Relative humidity usually ranges between 75% and 85%, with October and November topping the charts. The mix of cool air and high moisture makes it feel colder than the numbers suggest.
Mornings and evenings are especially damp. Fog and mist aren’t unusual, particularly in October when the air cools fast after sunset.
Rain falls more often in September and October than in November. Even on dry days, the air holds enough moisture to create a lingering chill.
If you’re heading outside, dress in layers that resist moisture. A light waterproof jacket helps, since the damp air can cling to your clothes and make you shiver.
Typical Wind Speeds
Winds in Stockholm during fall usually stay moderate but can feel brisk thanks to the city’s coastal spot. Average wind speeds hover around 8 to 13 mph (13–21 kph), but gusts can get stronger when Atlantic weather rolls in.
September brings lighter breezes, but October and November get a bit more blustery. By late fall, winds feel sharper as temperatures drop near freezing.
Wind direction matters. Westerly and southwesterly winds bring milder, moist air, while northerly winds drag in cold from the Arctic. You’ll notice the difference in how cold it feels, sometimes even day-to-day.
Open spots like waterfronts, bridges, and squares always feel windier than sheltered streets. If you’re walking or biking, you’ll definitely notice the chill in those places.
Sea Temperatures Around Stockholm
Water around Stockholm cools down fast in the fall. You’ll see a steady drop from late summer warmth to near-freezing levels by early winter. This change affects swimming, boating, and other water activities.
Baltic Sea Water Temperature Trends
In early September, the Baltic Sea near Stockholm usually sits around 60°F (15–16°C). That’s still okay for a quick swim, especially if the sun’s out. By October, the average drops to about 52°F (11°C), and the water starts feeling way too cold for casual swimming unless you’re wearing a wetsuit.
November brings a sharp drop. Average sea temperatures fall to roughly 43°F (6°C), with lows near 41°F (5°C). At this point, the water is really cold, suitable only for cold-water swimmers or folks with the right gear.
By late fall, the cooling trend continues, heading toward winter averages near 33–36°F (1–2°C). Water this cold isn’t safe for long exposure. If you plan to go boating or kayaking, get ready for icy winds and the risk of sudden chills from splashes.
| Month | Avg Temp °F | Avg Temp °C |
|---|---|---|
| September | 60°F | 15–16°C |
| October | 52°F | 11°C |
| November | 43°F | 6°C |
