In May, Iceland shifts from winter to spring with average highs around 9°C and lows near 4°C. Daylight stretches to nearly 18 hours, but the weather stays unpredictable—expect rain, wind, and occasional snow, especially in the highlands. Bring layers and waterproof gear.
What is the typical weather in Iceland in May?
May brings the first real spring thaw along the coast. Reykjavík sees average highs of 9°C and lows of 4°C, while Akureyri in the north is slightly cooler. Precipitation runs about 50–60 mm for the month. Snow is still possible at higher elevations or in the mountains, but lowland snow is rare and usually melts quickly. Compare this to Greece weather in May, where you get warm, dry Mediterranean conditions.
Can you see the Northern Lights in Iceland in May?
By May, twilight never truly fades in southern Iceland, making the aurora difficult to spot. The season for Northern Lights generally ends in April. If seeing the aurora is your priority, plan for October through March instead. Late May offers long daylight for hiking but not dark skies.
Is there snow in Iceland in May?
Snow can still fall in higher elevations and north-facing slopes, but coastal areas usually see rain, not snow. If you’re planning to visit the interior or drive the highland roads, check road conditions at vedur.is.
How does May compare to June weather in Iceland?
June is warmer (averages 11–13°C) and has even longer days—up to 21 hours of daylight. Rain is similar, but snow is very rare. Many travellers choose late May as a transition month with fewer crowds than June.
What is the weather in Iceland in late May?
Late May brings the longest daylight of the month, often with more stable weather than early May. Temperatures may reach 12°C on calm days. It’s a good time for hiking the south coast or exploring Canada weather comparisons, though sea breezes stay cool.
