Weather in Iceland in May

The most settled conditions in May tend to come in the southwest and the sheltered towns of the south coast, where the climate is generally milder.

• Reykjavik: Warmest Regions in May: Paleokastritsa on Corfu's western coast enjoys sunny, sheltered days in May, with average temperatures comfortably in the low twenties Celsius. Its pebbly coves, turquoise water and gentle sea breezes make it one of the island's most pleasant spots for swimming, walking and relaxing by the sea before the summer crowds arrive. It is exactly the brief our Reykjavik holidays deals are built around.
• Reykjanes Peninsula: The Reykjanes Peninsula sits a short drive from Keflavik Airport and is often sheltered from the worst of the northern weather, which makes it a practical stop on arrival or departure. Its lava fields and geothermal spa are easy to reach, and the lower-lying terrain tends to feel less exposed than the highlands. Conditions can still turn quickly, so we suggest keeping your plans flexible. For travellers wanting an easy first day, it is a sensible choice.
• Vestmannaeyjar: The Westman Islands lie off the south coast and offer a mild, maritime climate in which the sea moderates temperatures compared with inland areas. Ferry links from the mainland mean you can plan a day trip, though sailings can be affected by wind, so allow a margin in your timings. The islands suit visitors who enjoy coastal walks and birdlife at this time of year. Our view is that they reward a relaxed pace rather than a packed itinerary.
• Hafnarfjordur: Hafnarfjordur is a harbour town just south of the capital, and its sheltered setting usually means somewhat calmer conditions than the open coast. It is close enough to the capital for an easy day out, with a relaxed centre and coastal paths to explore. The town works well as a base if you want a quieter night than the capital offers while keeping city access nearby. We recommend it for visitors who value convenience alongside a gentler setting. It is exactly the brief our Iceland Luxury Holidays deals are built around.
• Grindavik: Grindavik is a fishing town on the Reykjanes coast, where the harbour gives a working, unpolished feel and the surroundings are open to the Atlantic. Winds can be strong here, so the mild label applies more to the sheltered parts of the day than to exposed walks. It is well placed for those combining the Blue Lagoon with a coastal stop. Our judgement is that it suits travellers who want a practical base on the peninsula.
