Traveller notes on Anchorage in March

Other months in Anchorage

Regulars describe a real range within the month - anywhere from below-freezing and snowy to cold and rainy to sunny and warm - with conditions specifically noted to get markedly worse later in the month than earlier. Our row backs the cooling, wetter read, 14.1C over 6.4C nights feeling 5C, with 71.3mm of rain across 12.1 days and a trace of early snow, 1.2cm. Regulars are specific that fall colors peak in late August to early September, so by mid-month leaves are already falling with trees turning from green toward yellow rather than at their most vivid. One mid-September visitor's own report described a genuinely pleasant trip, highs in the 50s-60s Fahrenheit and lows in the 30s. The sea sits at a cold 12.8C. The record: 6.8 hours of sun, an 8.9 kph wind and one of the cleanest air readings in this project, AQI 19.

May splits in two here and locals use their own word for the first half: breakup, when the thaw turns trails to mud and slush and some of them are still snow. Late May is a different month - they call it some of the best weather of the year - and the shoulder rates run to about the 1st of June, with the summer season proper from mid-May. Our row shows the transition: 14.6C days over 5.3C nights, 2.8cm still in the snow column, and 26.1mm of rain across 4.6 days, one of the driest months. The daylight is already 17.6 hours. The sea is 3.5C, which is not a swimming number. The record: humidity 76 percent, 11.4 hours of sun and AQI 31.

August is statistically the wettest month in this part of Alaska and regulars neither deny it nor dramatise it: light rain here and there rather than all day every day, plenty of cloud, and genuinely fine days in among it. May and June are the dry months, July and August the wet ones, and the clear weather tends to return at the very end of August into September. Our row gives 94.4mm across 13.3 days with 18.9C by day and 11C at night, and 15.7 hours of daylight to use them in. The silvers start running towards the end of the month. Nothing stops for the weather, so the answer is clothing. The record: humidity 81 percent, 8.8 hours of sun and AQI 22.

July in Anchorage runs from overcast, cool and rainy to bright and sunny, and regulars are honest that the best weather often comes earlier, in May and June. Their packing answer is the same whatever the forecast says: layers - a t-shirt, a fleece and a lightweight rain jacket - with enclosed shoes rather than sandals and a long-sleeved shirt that doubles as mosquito cover. Anything on the water is much colder than the town, so a hat and gloves go in the bag too. The other July fact is the light: our row gives 18.3 hours of daylight, and the practical advice attached is to bring an eye mask if that will keep you awake. The record: 20.6C days, 12.5C nights, 8.9 precipitation days carrying 59.2mm and AQI 23.

    26 Feb – 8 MarMajor festivalCrowded

    Ten days of winter carnival downtown at the end of February: sled dog sprints on Fourth Avenue, outhouse races, snow sculpture and the running of the reindeer. It is the one time the city treats February as an asset. Source ↗

    On the first Saturday in March the teams run a slow eleven miles through downtown for the crowds before the real restart in Willow the next day. Fourth Avenue is trucked full of snow for it and closes from dawn. Source ↗

  • Nature

    Aurora season

    20 Aug – 15 Apr

    From late August the nights are dark enough again. City light washes out all but the strong displays, so the trick is a twenty-minute drive north or up Glen Alps and away from the bowl.
