With 12 daily sunshine hours and only 14 rain days, this month delivers genuinely reliable outdoor conditions, ranking it the sunniest month of the year in Reykjavik.

Budget-conscious visitors will find the best value of the year in this period.

What to Wear in Reykjavik in June
Packing for Reykjavik in June means dressing for 13°C days and 7°C evenings. A mid-weight jacket over a sweater handles 13°C daytime temperatures; the combination stays comfortable all day without overheating. Evening temperatures settle at 7°C, a modest 6°C drop that a light cardigan or denim jacket covers. European cobblestones reward low-profile walking shoes over flip-flops or heels, with cushioned trainers or leather walking shoes being the practical choice. With 14 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes.
Local tip: Reykjavik's cobbled streets turn slippery in the rain. Waterproof walking shoes with a non-slip sole outperform fashionable footwear on wet stone, and you'll cover significantly more ground in comfort.
Events in Reykjavik in June

Local restaurants, markets, and transport operate at a relaxed pace, making this an ideal time for visitors who prefer a more authentic, unhurried experience of everyday city life rather than large crowds drawn in by a single major headline event.
