Blue Lagoon in August

Winter months from November through March offer the most dramatic experience. Picture yourself in steaming blue water while northern lights dance overhead - that's peak Blue Lagoon. The contrast between hot water and freezing air creates an almost mystical atmosphere. Summer brings midnight sun and easier access, but also maximum crowds and higher prices. Shoulder seasons in April-May and September-October give you decent weather with fewer people. Avoid July and August unless you enjoy sharing your zen moment with tour buses.
