Ask travel professionals who know Iceland for the smartest month to visit and a striking number whisper the same answer: May. It delivers most of summer’s access (18 to 21 hours of daylight, open roads, active wildlife) at shoulder season prices and pre crowd serenity. The only things missing are the highland interior and the last few degrees of warmth. Almost everything else is already on the table.
The May Equation
Daylight runs from 16.5 hours to over 20 by month’s end, with no true darkness from mid May onward. Temperatures reach 39 to 50°F (4 to 10°C), the countryside turns green week by week, and the lupine bloom begins in the south, purpling whole valleys by late May. Hotels still price like spring. Tour availability is wide open.
The Best Things to Do in Iceland in May
1. Drive the Ring Road in Its Quietest Good Month
All of Route 1 is comfortably open, the days are functionally endless, and the camper vans of July have not yet arrived. May is arguably the single best month for the full circuit: ten days, no crowds at Jökulsárlón, golden evenings that last until midnight.
2. Puffins at Full Occupancy
By May the colonies are fully staffed: the Westman Islands’ millions, Dyrhólaey’s accessible cliffs (note partial closures for nesting in early season), Látrabjarg in the Westfjords, Borgarfjörður eystri in the east. The birds court, burrow, and pose all month.
3. Whales Hit Their Stride
Húsavík and Eyjafjörður sailings deliver high humpback hit rates from May onward, with minkes, dolphins, and the season’s first blue whale sightings in good years. Seas are statistically calmer than midsummer storms suggest.
4. Waterfalls at Maximum and Lupine at the Start
Snowmelt keeps every major fall at full volume while the Alaskan lupine paints the south coast purple from late May: the Vík dunes and Skógafoss approaches become the photographs of the season.
5. Hike the Newly Opened Lowland Trails
May opens the great lowland hikes before the highland classics: Glymur’s full loop (the log crossing returns for the season), Fimmvörðuháls in its late May window for the experienced, Reykjadalur’s hot river without winter ice, and the Snæfellsnes coastal paths in nesting bird company.
6. The First Festivals
Reykjavík Arts Festival fills late May with international theatre, music, and visual art, and Seafarers’ Day looms at the start of June: the cultural season’s opening stretch.
7. Golf Under the Almost Midnight Sun
Courses reopen across the country and late evening tee times return. By month’s end, a 10 pm round in full daylight is routine, weeks before the Arctic Open crowds arrive.
8. Bathe in Transition Weather
Lagoon strategy in May: outdoor soaks in single digit air with 20 hour light, the Mývatn Nature Baths before the northern crowds, and the season’s first comfortable natural hot pot hunting in the Westfjords as their roads clear late in the month.
May Practicalities
Pack the eternal three layers plus a sleep mask, which becomes essential equipment from mid May. The highlands (Landmannalaugar, Askja, Þórsmörk’s F roads) remain closed; do not plan around them. Book the Westman Islands ferry ahead for late May weekends. A 2WD now suffices for the entire Ring Road.
