I was there this March and must say it was one of the most frustrating trips I had ever made. The weather is as unpredictable as imaginable.it may snow, rain, be sunny, windy, or complete blizzard all within A 20 minute period.because of these unpredictable weather patterns I would stick to the south western part of the island. This gets you the ice beach, the blue Lagoon, Gullfoss and Vik.Bring tons of microfiber lens cleaning cloth's and rain gear.
