The average temperature in Longyearbyen varies from -14°C in winter to +6°C in summer. During winter it is not uncommon that the temperature is between -20 and -30 degrees in longer periods. Combined with wind, the effective temperature may get close to -70°C. Several layers of wool are needed, as well as wind proof outer clothing, and, of course, no bare skin.

Svalbard is an arctic area where also the summer can be relatively harsh. Short pants are a seldom sight while it is almost always necessary to have wind proof clothing available. We can have fantastic fair weather, but you should also have a hat and gloves at hand. The need for equipment varies with the kind of activities you wish to engage in.
