Ill be going to Reykjavik this coming thursday. I have been looking ahead at the weather forcast and it looks like snow and rain for the days i will be there. I was just wondering if when it rains does it rain all day? Or just for a little while? Id like to book a northern lights tour but with this forcast I feel i wont see anything. If anyone can kind of give me a heads up as to when rain and snowy weather in Iceland in March is like id really appriciate it.
