Weather in July

July is the main summer month in Iceland and one of the warmest times of the year to visit. The average temperature is around 10.6°C (51°F), but it is often warmer than that, and some days can climb to 20°C (68°F) or higher. July is when Iceland feels at its most open, green, and full of life.

Do not be surprised if you see Icelanders in shorts and T-shirts, enjoying the sunshine on their patios or spending time at local swimming pools. July also brings the most sunshine of the year, with around 171 hours on average, and the days stay bright almost around the clock. If you are sensitive to light, it is worth bringing a sleeping mask.

In the past, East Iceland has often been one of the warmest parts of the country, and temperatures there can reach 20 to 25°C (68 to 77°F). Rain is still always possible in Iceland, even in July, and summer nights can feel cool, so it is best to be ready for a mix of conditions. July is also excellent for wildlife, with birdlife in full summer activity and great opportunities for whale watching.

Driving in Iceland in July

July is one of the very best months to rent a car in Iceland and go on a road trip around the country. Roads are easier to travel than in winter, there is no snow or ice on the main routes, and the long bright days give you a huge amount of flexibility for sightseeing. It is an ideal time for Ring Road travel, scenic detours, and longer summer journeys.

Even in July, Icelandic weather can still change quickly, so it is important to check road and weather conditions before heading out. If you plan to travel to more remote regions or into the Highlands, a 4WD is still a smart choice. Off-road driving is strictly forbidden in Iceland, and it is always important to stay on marked roads and tracks.

Most roads are open in July, including many mountain roads that begin opening from mid-June into July depending on conditions. July is a fantastic month to take advantage of Iceland’s long bright nights, visit places like the Westfjords, and combine your self-drive trip with guided experiences. Current July tour cards on the page include Hike to Volcanic Eruption Sites & Reykjanes Tour, Ice Cave under Katla Volcano, Glacier Walk Solheimajokull, and Whale Watching Husavik.

If you are not comfortable driving yourself, many bus tours and private tours are also available during the summer season in Iceland.

What to wear

July is one of the warmest months in Iceland, but summer weather here still calls for layers. Bright sunny hours can feel pleasantly warm, while evenings, windier areas, and rainy spells can still feel cool. The best approach is to pack for flexibility rather than heat alone.

The average summer temperature in Iceland is around 10°C (50°F), but warmer days can go much higher, while cooler days may still feel fresh. Weather can shift quickly from sunshine to rain, so it is smart to bring clothing that is easy to add or remove during the day.

We recommend bringing layers, comfortable walking shoes, a sweater or fleece, and reliable rain gear. July is also a month when lighter summer clothes can absolutely be useful, especially on warmer inland or eastern days.

• Hiking boots – If you are only staying in Reykjavík, sneakers may be enough, but if you will be traveling around the country and spending time outdoors, proper hiking shoes are a much better choice.
• Base layer – Many travelers are comfortable with regular summer clothing in July, but if you get cold easily, a light thermal or wool base layer is useful.
• Fleece or wool – A fleece jacket or traditional Icelandic wool sweater is ideal for cooler evenings and breezier days.
• Waterproof and windproof jacket – A good outer layer is essential for rainy weather and exposed areas.
• Waterproof pants – Very useful for wet trails, waterfalls, and changeable weather.
• Hat, gloves, and warm socks – Optional for some travelers in July, but still worth packing for cooler nights or windy areas.
• Swimsuit – A must for Iceland’s swimming pools, hot springs, and geothermal baths.
