Don’t leave your coat at home:  Iceland’s weather can be unpredictable and can change rather dramatically within a single day. So no matter how pleasant the weather may seem at the time, make sure you never leave without a warm coat in tow. Don’t underestimate the weather: While the temperature range isn’t drastic. It can go up to +20 degrees Celsius in high summer and doesn’t usually get lower than -15 degrees Celsius in winter. And despite its name gets very little snowfall. It’s the wind you need to look out for here. Expect constant winds near the sea – from mild gusts to blowing gales. There’s even a local joke that when there are calm winds in Iceland, it means the entire North Atlantic is experiencing calm winds. Keep safe at beaches: Iceland has some beaches which are not safe for swimming. For instance, Reynisfjara has claimed a few lives. When you see warning signs in Iceland that something is dangerous, adhere to them. Don’t stand too close to the water’s edges or turn your back on the waves. Not even for a selfie. Don’t stand on any ice: When exploring glaciers don’t walk on top of a glacier without a certified mountaineer guide. Just don’t. The surface ice may look lovely and strong, but ice can easily break and send you into icy depths. Avoid shopping at 10-11: If you have a late flight, a 10-11 may be your only choice, but wherever possible steer clear of this supermarket chain. Simply because it’s the most expensive supermarket in Iceland, and prices here are sometimes three times higher than at the cheapest alternative. Save money by shopping at Bonus, Kronan, or Netto stores. Use proper etiquette when visiting baths and pools: Always follow all rules when visiting baths and pools. For instance, if you are required to shower before you enter, make sure you do so.
