Overview of Iceland's Weather
Iceland’s weather is a fascinating mix, shaped by its location near the Arctic Circle and the warm waters of the Gulf Stream. Even though Iceland is pretty far north, that Gulf Stream keeps the island’s climate milder than you’d expect. The weather can change quickly, so it's not unusual to experience a bit of sunshine, wind, rain, and even snow all in one day!
Throughout the year, the temperatures stay fairly moderate. Summers (June to August) are cool, with highs usually between 50°F and 59°F (10°C to 15°C), and sometimes you'll even get a rare warm day around 77°F (25°C). Winters (December to February) are cold but not unbearable, with average temps around 30°F (-1°C). Snow is common in the colder months, but rain can pop up any time of the year, especially in the southern part of the island.
Iceland’s weather also brings some pretty cool natural events. In the summer, the Midnight Sun gives you nearly 24 hours of daylight, perfect for exploring. And in winter, the long nights are ideal for spotting the Northern Lights. While strong winds and occasional storms can happen, it’s all part of Iceland’s wild, ever-changing charm that makes it such an exciting place to visit.

Other Factors that Influence the Icelandic Weather
Now that we have covered each month and season thoroughly, let’s discuss other factors that can affect the weather, such as daylight hours, snow, rain, and wind.
Daylight hours
Iceland’s daylight hours change a lot depending on the time of year. In summer, especially around June, the sun barely sets, giving you almost 24 hours of light—perfect for getting outside and exploring. In the winter, like in December, daylight drops to just 4-5 hours, making it great for seeing the Northern Lights. During spring and fall, the days are a bit more balanced, with about 8 to 16 hours of daylight, so you get a good mix of daylight and dark.
Snow
Snow in Iceland can be pretty different depending on where you are. In Reykjavík, snow usually appears between November and March, but it melts quickly because of the warmer coastal weather. Up north, in places like Akureyri and the Westfjords, snow can get much deeper, sometimes over a meter (3 feet) during winter. Reykjavík gets around 20-30 cm (8-12 inches), while the Highlands stay snowy most of the year. Some glaciers and mountain peaks even hold onto snow all summer!
Rain
Rain patterns in Iceland depend a lot on where you are. Reykjavík gets around 800 mm (31.5 inches) of rain yearly, spread out over about 147 rainy days. Up north, places like Akureyri are much drier, with only 400-600 mm (15.7-23.6 inches) of rain annually. The wettest times are usually March and October, with October seeing more than 100 mm (3.9 inches) in Reykjavík. The Westfjords, though, get way more rain—up to 2000 mm (78.7 inches) each year because of all the mountains nearby.
Wind
Iceland's wind can be pretty intense, especially in the winter months when gusts can hit over 70 mph in areas like the south coast and the Westfjords. Even during the calmer summer months, winds can still reach around 45 mph near glaciers and in the highlands. The windiest times are from January to March and October to December, so it's important to pack windproof gear and keep an eye on the weather forecast. Be ready for sudden gusts, especially when driving or hiking in exposed areas.
Conclusion
Iceland’s weather is unpredictable, but that’s part of the fun! Every season has its charm, from long summer days filled with light to winter nights perfect for spotting the Northern Lights. No matter when you visit, being ready for whatever the weather throws your way will help you enjoy every moment of your adventure.
