Comfortable days, but keep a warm layer handy

The daytime average suits walking and spending time outdoors more than sitting about in swimwear. Warmer spells do happen: the warmest 10% of days reach around 22°C or more, so lighter clothes still deserve space in your bag. The catch is the drop in temperature later on. Nights average 11°C, and the coldest 10% fall to around 8°C or below. Pack layers you can add rather than relying on summer clothes alone. A jumper and a jacket will make evening plans more comfortable, while clothes that work across mild and cool conditions are more useful than a wardrobe built for heat.

Long days do not mean constant sunshine

July gives you about 17.8 hours of daylight, but only around 5.3 hours of sunshine a day. That leaves plenty of time for outdoor plans without promising clear skies. With about 16 rainy days, rain needs to be part of your packing and planning rather than treated as an unlikely interruption. A waterproof jacket and footwear you are comfortable wearing in wet conditions are sensible choices. Keep outdoor plans flexible enough to take advantage of brighter weather, and leave room for time indoors. The appeal is the long window for getting out, not dependable dry weather from morning to evening.

The sea is cold, even in the warmest month

Sea temperatures average around 14°C, with a year-to-year range of 12°C to 16°C. That is cold water, not the sort of summer sea in which most travellers will want to linger. If comfortable swimming is central to your holiday, July in the fjords is a poor fit despite being the warmest month on land. Think of swimming as an optional cold-water activity rather than the main reason to go, and do not let a mild afternoon persuade you that the water will feel warm. Pack for staying comfortable beside the water, with something warm and dry ready if you do choose to get in.
