July weather forecast
South Georgia and the South Sandwich Islands

July stands as the peak of the Antarctic winter in South Georgia and the South Sandwich Islands. This month is often the coldest, with average temperatures plunging between -5°C (23°F) and 1°C (33.8°F).

Even in Grytviken, the marginally milder conditions of previous months give way to the pervasive cold. The moderating influence of the ocean is insufficient to fend off the freezing temperatures that define this time of the year.

Wind speeds remain high in July, averaging 30km/h (18.6mph). Intense storm events are a regular occurrence, during which wind speeds can surge significantly higher. These storms, coupled with the frigid temperatures, often create harsh and challenging weather conditions.

Snow is the primary form of precipitation in July. Due to the persistently low temperatures, even coastal regions receive regular snowfall. This is especially true in higher altitude regions where snow accumulation is substantial, frequently leading to extensive snow cover across the islands.

Wildlife activity is at its lowest during July, with only a few resilient species remaining. The majority of bird and marine life that once teemed during the warmer months have sought refuge in milder climates.

Compared to June, the weather in July is more severe, holding the title as one of the coldest and snowiest months of the year. As the islands transition into August, these extreme conditions endure, with minimal improvements expected. Temperatures remain consistently low, wind speeds continue to be high, and heavy snowfall is commonplace.
