The best time of year to see the Northern Lights in Iceland is between the months of September and March. To be in with a really strong chance to witness the northern lights a cloudless, clear sky is the main requirement with the outside temperature being cold but dry.
I spent four nights in Iceland; four chances to see the northern lights. The first night, I booked a stay in the small town of Hveragerdi, about a 45-minute drive from the light pollution of Reykjavik. When conditions align, the outdoor thermal hot tubs of Frost and Fire Guesthouse are an ideal viewing spot.celand is one of the world's most accessible spots for viewing the northern lights, making it one of the country's top tourist attractions.
