Forum posters describe September in Sweden generally as a good time to visit once the summer crowds thin out, though weather is genuinely unpredictable - conditions can range from a warm, sunny 25C spell to a cold, rainy 12C stretch within the same month, with early September typically a safer bet than the back half, which tends to turn rainier. Posters recommend a flexible layering system: t-shirts for a mild day, a medium-weight sweater or cardigan for cooler stretches, and a lightweight water-resistant coat for when the rain arrives. As a mountain town well north of Stockholm, Are itself should be expected to run cooler and see more rain days than the milder southern-Sweden figures posters typically quote, given both the latitude and elevation.

Forum posters describe December in Trondheim as bringing short, cold days with ground typically covered in snow, noting that locals lean toward cross-country skiing rather than walking this time of year. Posters are direct that heavy snow arriving right before or during a visit can rule out most walking plans entirely, though the tram ride up to Lian is consistently flagged as a safe, reliable option regardless of conditions. Posters consistently recommend wool long underwear along with a hat and gloves as genuine essentials, noting that special outerwear pants aren't really needed for strolling around the city itself. Posters flag that many students leave for the holidays, leaving Trondheim noticeably quieter than usual through late December. Posters generally rate December as workable but genuinely weather-dependent, with flexibility the key to enjoying a winter visit.

June in Trondheim barely gets dark — over twenty hours of daylight — and the forum's own saying is that if you are not happy with the weather, give it five minutes. Expect 10 to 20°C, some nights down to 5, occasional days above 25, and the honest possibility of cold, windy and rainy instead. They call June relatively dry, though the record still shows rain on about thirteen days. The packing list is a list precisely because you may need all of it: windproof and waterproof shell, a woollen sweater, long trousers, hiking shoes, and shorts. June versus July is not worth agonising over — the difference is statistical.
