Weather in May
May brings considerable changes to the
Þorlákshöfn weather pattern, as
Iceland kicks into the spring season properly. Sea temperatures hike up to an average of 7.6°C (45.7°F) and daylight hours increase significantly. As a result, May is a pleasant time to wander around and enjoy the blooming lupine fields that cover the country. Wildlife viewing, particularly bird watching, reaches its peak during this month.
