מזג האוויר באולסון במרץ

Regulars are direct this is genuine autumn here, cold nights and often rainy days the norm, with a small chance of snow reaching the surrounding mountains early in the month, though unlikely enough to close roads. Our row backs that cool, genuinely wet read, 16.9C over 8.1C nights feeling as low as 5C, with a substantial 260.9mm of rain across 19.3 days and a trace of early snow, 0.2cm. Regulars are consistent a lucky stretch of good weather makes this a genuinely good time to visit precisely because of fewer visitors and a better choice of accommodation than peak summer. Wind, rain gear and a properly warm layer remain the standard advice regardless of how any single day starts. The sea sits at a cold 14.6C. The record: humidity 84 percent, 7.3 hours of sun and a 23.5 kph wind.

April here still counts as winter to regulars - cold, wet, windy, and they put the average around 4C, close to our 5.7C. What varies is how far that winter has retreated: at the coast and in the lower fjord towns the snow is mostly gone by mid-April, while the mountains all around stay covered, which is exactly what our 27cm of snowfall column is measuring - hills, not streets. Our row gives 10.9C by day reading as 7C, nights at 0.4C feeling -4C, with 128mm of rain across 14.2 days, one of this coast's wetter columns even in an otherwise drier month by local standards. Roads stay open and salted, so a cold week does not close anything. The sea is 7.2C. The record: humidity 78 percent, 10.4 hours of sun, a 22.8 kph wind and AQI 40.

Regulars on the western fjords answer an August question with a statistic and a shrug. The statistic: August is slightly wetter than July, which is slightly wetter than June, though it is also the warmest of them. The shrug: the west is simply a wet place, grey is part of the experience, and long-range forecasts are an indication at best - warm, cold, rain and sun can all arrive in one day. The range they tell people to pack for, 10 to 20C with 20 to 25C on a good day, is our row almost exactly at 19C over 10.8C. Rain rarely runs all day and is often a drizzle a westerner would not call rain. The record: 192.3mm across 19.8 days, 9.3 hours of sun inside 16 of daylight, and a 14.4C sea.

Regulars put May in Alesund between 40 and 60F, adding that the low end is rare on the coast by late May; our row's 15.5C over 5.4C is exactly that span, reading as 13C and 2C in the wind. They are equally direct that the western fjords are a wet coastal climate with notoriously variable cloud, so rain or grey is part of the trip rather than bad luck - 98.1mm across 15.2 precipitation days here. What the wet month buys is the thing people come for: snow still on the summits, green below, and countless waterfalls between the two. Our 6.8cm of May snow is those summits inside the grid square. The record: 11.8 hours of sun, 17.9 hours of daylight, an 8.4C sea and AQI 39.
