Погода: Илулиссат, январь

Forum posters are direct that Ilulissat sits in polar night through December and January, with the sun not rising at all from late November to mid-January - dawn and dusk each last roughly two hours at this latitude, so there's a meaningful twilight window around midday even without a true sunrise. Posters describe January temperatures typically around -20C, with -30C not at all unusual, alongside genuinely unstable weather that can delay flights in or out by several days. Posters note town streets stay lit so getting around after dark isn't an issue, and a handful of tour operators still run boat trips among the icebergs when the sea stays unfrozen and there's enough midday light. Posters generally frame January as a viable but genuinely low-season visit, with far fewer tours running than in the brighter months.

Regulars are specific early in this month still runs as cold as December, genuinely deep winter, with lows capable of dropping to -25 to -30C on the coldest nights even though the average sits milder than that. Our row backs that cold, genuinely dry read, -0.2C over -8.5C nights feeling as low as -13C, with rain light at 20.8mm across 5.3 days and real snow, 19.4cm. Regulars are consistent the iceberg boat trip and the icefjord boardwalk hike stay reliably doable throughout, though other hikes need snowshoes and the very last week can be an awkward in-between - too much snow for summer activities, not enough stable ice yet for full winter ones. Seal fur clothing and boots are rentable locally rather than something to pack. The sea sits at a frigid -1.6C. The record: humidity 75 percent, 10.6 hours of sun and a 15.3 kph wind.

Ilulissat-forum threads on September weather describe a genuine autumn transition: this is the wettest month of the local calendar, the first snow of the season typically arriving late in the month or slipping into early October, and posters are candid that recent years have run unusually foggy and unpredictable even by Greenland's own standards. The standing advice is to build real flexibility into any itinerary and keep money aside for cold-weather gear that turns out missing from the packing list - conditions here can outrun what a visitor planned for. The trade-off for the rougher weather is a genuinely strong month for the northern lights as nights lengthen, even as whale sightings drop off from summer's peak. Regulars call the autumn colors against the icebergs a real payoff. The record: a raw 4.9C by day dropping to -0.7C at night, 46mm across 8.1 days, 7.3cm of fresh snowfall, 74 percent humidity and a 4.5C sea.

Greenland-forum threads comparing May to June are candid that May is an awkward in-between for Ilulissat: not enough snow left for winter activities, not warm enough yet for summer ones. The upside late in the month is real, though - the warmest stretch of May and the approach of the midnight sun bring 23 to 24 hours of daylight before mosquito season has even started. Icebergs need no timing at all; they calve and drift through Disko Bay year-round regardless of month, though how much sea ice is still around depends entirely on how cold that particular winter was, sometimes lingering into early May. Boat trips out to the Eqi glacier don't start until June, and almost everything else here is weather-dependent day to day. More than one poster ends up recommending June over May for exactly that reliability gap. The record: 4.1C days feeling like 0C, -2.4C nights, 24mm across 6.1 days, 14cm of fresh snowfall still falling, 72 percent humidity, nearly 22 hours of daylight and a 0.5C sea.

June in Ilulissat is round-the-clock light - our row gives 24 hours of daylight - and the forum's advice is to use both halves of it: an iceberg cruise by day and another at night, because the midnight sun turns the ice gold and there is no sunrise or sunset to wait for. Early June is not yet peak season, so those cruises are uncrowded, and the mosquitoes that plague later summer are not out. Two practical notes. It can be too icy to navigate well in June, with boats crawling because the fjord is hazardous. And it is cold on the water whatever the shore feels like - thermals, wool, a windproof layer, hat and gloves - which our row supports at a 2C night that feels like -2, and 6.1cm of June snow. The record: 8.4C days, 27.9mm of precipitation and a 1.4C sea.
