Reykjavík in July is Iceland's peak summer — 15°C / 59°F afternoons, 9°C / 48°F mornings, 20h of daylight. The warmest the country gets, still requiring a wool sweater.
Reykjavík in July is Iceland's peak summer. Veðurstofa Íslands data put afternoon highs at 15°C / 59°F and lows at 9°C / 48°F with 10 rain days. The 20 hours of daylight tilts the city's rhythm later — restaurants stay open, music venues run, locals walk the harbor at midnight in still-clear sky. The dressing rule continues: merino wool base, lopapeysa, 66°North windproof shell, waterproof boots, wool socks, hat and scarf for wind chill. The 9°C / 48°F low at 'night' (which is functionally twilight) means even peak-summer Reykjavík requires layers. July is the strongest month for the highlands — Landmannalaugar (the rainbow mountains), Þórsmörk (the valley between three glaciers), the Westman Islands (puffins), and the Snæfellsnes Peninsula (Iceland's most-photographed mountain Kirkjufell) are all fully accessible. The Reykjavík Pride parade falls in August, but July hosts other festivals: Reykjavík Folk Festival, the Solstice Festival, Innipúkinn music festival.
Reykjavík in July is the peak month for the puffins, the Westman Islands, and the highland tracks to Landmannalaugar — Iceland's interior fully accessible, the air stays soft 20 hours a day.

Yes — July is Iceland's warmest month with average daily high of 15°C (59°F) and low of 9°C (48°F). Per Veðurstofa Íslands. Daylight is 20 hours; the city stays in functional twilight at 'night.' Wind speeds run 15-25mph year-round. The temperature is significantly cooler than continental European summer (Paris July is 26°C / 79°F, Rome 31°C / 88°F; a wool sweater stays in daily rotation.
All of them — July is the only month with full highland access. The most-photographed routes: Landmannalaugar (rainbow rhyolite mountains, 4-hour drive from Reykjavík; requires 4WD or guided tour), Þórsmörk (the valley between Tindfjallajökull and Mýrdalsjökull glaciers), the Westman Islands (puffin colonies, ferry from Landeyjahöfn), Snæfellsnes Peninsula (Kirkjufell mountain, the most-photographed in Iceland). Pack: merino base, lopapeysa, 66°North shell, waterproof boots, wool socks, hat + scarf + gloves, sunglasses, water, snacks. Day trips run 8-14 hours.
The Westman Islands (Vestmannaeyjar) — the world's largest Atlantic puffin colony, accessible by 35-minute ferry from Landeyjahöfn. The puffin nesting season is mid-April through August; July is peak. Stórhöfði is the most-cited viewing point. Bring binoculars, waterproof shell, wool layers (the open Atlantic wind is significant), waterproof boots. Excursions also run from Reykjavík harbor to the smaller puffin islands of Akurey and Lundey, but the Westman Islands are the most-photographed colonies.
Dill — the only Michelin-starred restaurant in Iceland, serving New Nordic cuisine using Icelandic ingredients (smoked fish, Icelandic lamb, foraged plants, fermented dairy). Booking 2-3 months ahead is required; the tasting menu runs 8-10 courses. For a more accessible alternative: Matur og Drykkur (Old Reykjavík traditional with creative interpretation), Snaps (French-Icelandic), or Fiskmarkaðurinn (the city's most-cited fish restaurant). Skip tourist-heavy spots near Hallgrímskirkja for dinner; quality runs lower at the prime tourist locations.
Layered base + lopapeysa + 66°North windproof shell + waterproof boots + wool socks + hat + scarf. The lopapeysa stays in daily rotation even in 15°C / 59°F peak summer. The wardrobe palette runs muted (cream, charcoal, navy, soft brown) with the lopapeysa pattern as the visual interest. Reykjavík reads minimalist Nordic; athletic wear and gym sneakers read tourist immediately. Icelandic brands worth knowing: 66°North (heritage outerwear), Geysir (clothing + lopapeysa), Cintamani (technical outdoor), Steinunn (designer womenswear), Farmers Market Iceland (modern lopapeysa-inspired knitwear).
