Reykjavik weather in July

July is Reykjavik's warmest month, with average highs of 13.5°C (56°F) and lows of 8.6°C (47°F). You'll experience around 85mm of rainfall spread across roughly 16 rainy days, but don't let that deter you—the city enjoys nearly 10 hours of sunshine daily. The famous midnight sun means you'll have continuous daylight for exploring, with the sun dipping just below the horizon for a few hours at night.

July coincides with Iceland's peak summer season. The city buzzes with energy as locals and tourists fill outdoor cafés, galleries, and waterfront venues. The Reykjavik Arts Festival often runs during this period, and the weather encourages vibrant street life. Expect moderate to high crowds at major attractions, though Iceland's vast landscapes mean you can easily escape into quieter terrain.

For 2026, July remains an excellent choice if you want genuine warmth by Icelandic standards and maximum daylight. Pack layers and waterproof gear—rain showers are frequent but usually brief. This month offers the best balance of pleasant weather, long days, and accessible hiking, making it ideal for most travelers.
