The best time to visit Geiranger is during the summer months, from late May to early September, when the weather is at its finest and all attractions and services are fully operational.During this period, you'll experience the mildest temperatures, typically ranging from 15°C to 20°C, and the longest daylight hours, sometimes stretching to 18-20 hours in June and July. This allows for ample time to explore the fjords and surrounding mountains.For those keen on outdoor activities, July and August are ideal. The hiking trails, such as the popular path to Storseterfossen waterfall or the challenging climb to Skageflå farm, are generally clear of snow and easily accessible. Boat tours, kayaking, and fjord cruises operate frequently, offering unparalleled views of the Seven Sisters waterfall and the Geirangerfjord itself.If you prefer to avoid the peak crowds while still enjoying good weather, late May/early June or late August/early September are excellent alternatives. You'll find fewer visitors, and the landscape is particularly stunning with blossoming flora in spring or the beginnings of autumn colours.
