September weather forecast
French Southern and Antarctic Lands

September in the French Southern and Antarctic Lands marks the commencement of spring, as the region begins to emerge from the cold grip of winter. Average temperatures gradually rise, typically ranging from 1°C (33.8°F) to 3°C (37.4°F). While this is still quite cold, it represents a significant warming compared to the subzero averages seen in August.

The Kerguelen Islands, an essential component of this territory, display the same warming trend. The islands experience a slight rise in temperature, aligning with the region's overall climate pattern. Even though freezing conditions can still occur, the end of September brings more frequent periods of above-freezing temperatures.

In terms of precipitation, September sees a transition from snowfall to rainfall. As temperatures rise, rain becomes more frequent, although snow showers can still occur, particularly at the beginning of the month. Despite these shifts, the weather maintains its unpredictability, with clear days potentially giving way to fog, rain, or snow.

The transition from August to September denotes a significant climatic shift in the French Southern and Antarctic Lands. With each passing day, temperatures gradually increase and daylight hours lengthen, signifying the diminishing influence of winter. As September progresses into October, the region will experience further warming, and the spring season will start to take hold more fully.
