Weather in July

July stands as the height of summer in Svalbard and Jan Mayen, featuring the warmest temperatures of the year and constant daylight due to the ongoing Midnight Sun phenomenon.

In Svalbard, July's average temperatures range from 5°C (41°F) to 8°C (46.4°F), making it the warmest month of the year. The capital, Longyearbyen, witnesses this summer bloom, with vegetation thriving under the 24-hour sunlight. Marine wildlife thrives in the relatively ice-free waters, and migratory birds are present in large numbers.

Over in Jan Mayen, July brings average temperatures from 5°C (41°F) to 7°C (44.6°F), also marking it as the warmest month. The Midnight Sun continues to shine, casting 24-hour daylight over the Norwegian military base and the rest of the island. This continuous daylight supports an active wildlife season and a vibrant, if sparse, vegetation cover.

Precipitation in both Svalbard and Jan Mayen during July is moderate, typically falling as rain, which contributes to the continued summer thaw. However, given the territories' Arctic location, occasional snow showers can still occur.

Compared to June, July maintains a similar temperature range and continuous daylight. As these territories transition into August, temperatures begin to drop slightly, and daylight hours start to decrease, indicating the onset of the short-lived Arctic autumn. Despite being the warmest period of the year, visitors should still be prepared for rapidly changing conditions and cooler temperatures, particularly during the night.
