מזג האוויר ברייקיאוויק בדצמבר

June gives more than twenty hours of sun here and no real darkness at all around the solstice, just a long dusk - our daylight column says 20.8 hours. The temperature is the part people underestimate. Regulars quote the mid to high fifties Fahrenheit; one who came at the end of June reports upper forties and low fifties and a lot of wind. Our row sits between them at 12.2C reading as 10C, with nights at 7.3C feeling like 4C in a 19 kph wind. Rain falls 86.2mm across 15 days. Layers with a windproof and waterproof shell, and the hoodie stays on in the evening. The record: humidity 79 percent, a 9.9C sea and AQI 34.

Forum posters describe February as usually snowy and cold, with one blunt 'reality check' thread calling it the coldest month of the year and warning of the possibility of storms - it's rain, sunshine and snow all in one day being a genuinely normal occurrence rather than an outlier. Daylight stays limited, sun up around 10am and down by 5-6pm, so posters plan full-day itineraries around that shorter window rather than assuming a long afternoon. The clear upside repeatedly cited: February is a strong month for Northern Lights viewing precisely because the nights are still long and dark, and posters consistently say the trade-off is worth it as long as you pack proper warm, waterproof layers and stay flexible with plans.

Forum regulars describe January as averaging around freezing but wildly variable day to day - anywhere from -10C to 10C, with snow, sleet, hail and rain all possible, sometimes simultaneously, often with high wind. Daylight is the other defining fact: roughly 5-6 hours depending on the exact date, with about an hour of usable twilight on either end. Tour operators plan itineraries around this deliberately, timing pickups and drop-offs so you're at outdoor attractions during the daylight window even if you leave and return to Reykjavik in the dark. Layered, wind- and waterproof clothing with waterproof footwear is the standard packing advice.

Reykjavik forum regulars are consistent that wind and rain, not cold, are what actually get you in September: “it is not the cold in general that gets you, it is the strong winds and the rain,” with a genuinely wind- and waterproof outer layer called the single most important item to bring. Readings run “low 50s°F during the day and mid 40s at night” typically, though “glorious sunshine and temperatures in the 20°C range” does happen on a lucky day. Mid-September sits deep in shoulder season — you'll have all the places to yourself as summer crowds thin, but some attractions and hotels start closing for the season around the first or second week. A cold night can bring a dusting of snow at the mountain passes or in the north. Our record: 10.7°C days, 5.9°C nights, 18.6 rain days, 0.9cm of snow and a 21.9kph wind — cool, wet and windy, matching the “wind and rain, not cold, is the real story” read.
