Our tours on Snæfellsjökull glacier are highly weather dependent. That's mainly due to two reasons. First, Iceland is located far up in the North Atlantic Ocean where it meets the Arctic Ocean. The warm Gulf Stream that runs north keeps the climate in Iceland relatively warm and moist compared to mainland locations of same latitude. But warm and moist air that's traveled up into the cold and calm Arctic region can be troublesome. Iceland is exactly where these different climates are combined, resulting in frequent weather changes and interference between the two.
The second reason is that Snæfellsjökull glacier is located on the end of a peninsula surrounded by ocean in almost all directions. That means it's very exposed to any weather from sea level up to 1446 meter elevation. This prominence tends to cause turbulent weather on and around the mountain. The weather is very unpredictable and can change from sunny summer weather to some of the most intense weather phenomenons seen on Earth in a short period of time. We've experienced hurricane force winds on one side of the mountain and absolute calm just 5 minutes drive away from that location. Blizzard and sunshine within the same hour, etc... Then there is just generally bad weather and sometimes perfectly fine weather for days.
So, please keep this in mind when booking our tours and make sure we're able to contact you in case we cancel tours due to weather.
