July weather forecast
Iceland

July is typically the warmest month of the year in Iceland, marking the height of the summer season. The average temperature varies between 11°C (51.8°F) to 15°C (59°F), with the southern and western coastal regions, such as Reykjavik, experiencing slightly warmer conditions due to the moderating influence of the ocean. Despite being the warmest month, temperatures in July are still mild by global standards.

Just like in June, daylight is abundant in July due to the phenomenon of the Midnight Sun. The sun barely sets, leading to nearly 24 hours of daylight and providing ample opportunity for outdoor activities at any hour. This period of constant daylight gradually starts to wane towards the end of the month, signaling the approaching end of the summer season.

Precipitation during July is variable, averaging between 50mm (1.97") to 60mm (2.36"). Rainfall, when it occurs, is generally light and does not last for extended periods. The southern and western coastal regions are usually the wettest due to the incoming Atlantic weather systems. Snow is virtually absent in July, except in the highest peaks and the interior highlands.

Wind conditions in July are relatively calm compared to the rest of the year, with average speeds around 12km/h (7.5mph). Despite the milder temperatures, the wind can still make the air feel slightly cooler, particularly during the evening and in more exposed areas.

July is an ideal time to visit Iceland for those who prefer milder weather and extended daylight hours. It is a prime month for outdoor activities, including hiking, wildlife watching, and exploring Iceland's natural wonders such as its waterfalls, geysers, and volcanic landscapes. While the chances of seeing the Northern Lights are virtually zero due to the prolonged daylight, the beauty of the Midnight Sun and the vibrancy of the summer landscapes more than compensate for it. Whether it is to enjoy the bustling summer festivals in Reykjavik or the serene beauty of the Westfjords, July offers a wealth of experiences to visitors in Iceland.
