Each year, on March 23rd, the global community observes World Meteorological Day, commemorating the establishment of the World Meteorological Organization (WMO) in 1950. This day highlights the pivotal role meteorology plays in ensuring the safety and well-being of societies worldwide. In 2025, we focus on the indispensable contributions of meteorologists stationed at the South African National Antarctic Programme’s (SANAP) remote research stations: SANAE IV in Antarctica, Marion Island, and Gough Island.
On this World Meteorological Day, we extend our gratitude to the meteorologists of SANAP’s overwintering teams. Their unwavering commitment and resilience in some of the most challenging environments ensure that we continue to deepen our understanding of Earth’s atmospheric processes, ultimately contributing to the safety and well-being of societies worldwide.
SANAE IV (South African National Antarctic Expedition IV): Located at 71°S, 2°W in Antarctica, SANAE IV. Meteorological observations are conducted year-round, providing critical data on atmospheric conditions in this remote region.
Marion Island: Situated at 46°S, 37°E in the Southern Indian Ocean. The island’s meteorological station collects essential weather data, contributing to climate studies and aiding in the understanding of global weather patterns.
Gough Island: Located at 40°S, 9°W in the South Atlantic Ocean, Gough Island has hosted a South African weather station since 1956. The station conducts hourly climate observations and upper-air ascents, playing a crucial role in monitoring weather systems that can impact South Africa.
Meteorologists assigned to these stations undertake year-long deployments, known as overwintering periods, during which they perform several critical functions:
Surface Observations: Conducting regular measurements of temperature, humidity, wind speed, and other atmospheric parameters to monitor and document local weather conditions.
Upper-Air Observations: Launching weather balloons equipped with instruments to collect data on atmospheric pressure, temperature, and humidity at various altitudes, which is vital for understanding weather patterns and forecasting.
Equipment Maintenance: Ensuring that all meteorological instruments and equipment are calibrated and functioning correctly to maintain the accuracy and reliability of collected data.
Data Management: Recording, analyzing, and transmitting collected meteorological data to the South African Weather Service (SAWS) and other relevant organizations for use in weather forecasting and climate research.
The data collected by SANAP’s overwintering meteorologists contribute significantly to:
Weather Forecasting: Providing accurate and timely data that enhance the precision of weather forecasts, benefiting maritime navigation, aviation, and local communities.
Climate Research: Offering valuable insights into climate variability and change, particularly in the understudied southern hemisphere regions.
Environmental Monitoring: Supporting studies on the interactions between the atmosphere and the unique ecosystems of Antarctica and the sub-Antarctic islands, aiding in the conservation of these fragile environments.

Every year, the South African vessel, the SA Agulhas II, embarks on a journey to Antarctica, marking the beginning of its annual research and supply voyage. This critical mission is not only a symbol of South Africa’s dedication to scientific research but also a lifeline for the overwintering team, personnel rotations, and vital logistical support for stations on the frozen continent. On the 15th of December, the SA Agulhas II departed from Cape Town, South Africa, bound for Antarctica. This voyage marks the commencement of a multifaceted operation, which encompasses research, supply deliveries, and personnel exchanges between Antarctica and the rest of the world.

The SA Agulhas II plays a pivotal role in supporting research and exploration in one of the most extreme and least understood environments on Earth. South Africa’s station in Antarctica, SANAE IV Station, rely on the vessel’s annual voyages for everything from scientific supplies to food, equipment, and fuel. The vessel also delivers critical scientific personnel, scientists, and engineers who are essential for conducting experiments, research, and environmental monitoring on the frozen continent.
This year, the SA Agulhas II will carry a group of researchers to continue studies on climate change, marine biology, and glaciology, among other fields. Another essential aspect of this annual journey is the personnel exchange that occurs as part of the overwintering team rotation. The team that has spent the harsh winter months at the research stations in Antarctica will return home, while a new team will take their place for the upcoming year.

The overwintering teams are a group of exceptional individuals who endure the Antarctic winter—a period marked by freezing temperatures, months of darkness, and isolation. They are responsible for maintaining research stations, conducting experiments, and ensuring that the infrastructure is operational during the harshest months. The rotation ensures that the same team does not endure multiple seasons of isolation and provides an opportunity for fresh perspectives and new expertise.
The SA Agulhas II is not just a research vessel—it’s a symbol of South Africa’s commitment to the exploration of one of the most remote places on Earth. The vessel’s crew is tasked with navigating the seas and icy waters that surround Antarctica, with the ship braving some of the world’s roughest weather and icy waters. The crew ensures the vessel stays operational throughout the voyage, providing safety and support to everyone on board. This year, as always, the vessel crew will work tirelessly to ensure that all operations go smoothly. They will transport cargo, assist scientists with their research, and ensure the safe arrival and departure of personnel.
We wish the SA Agulhas II, its crew, the overwintering team, and all personnel embarking on this important voyage a safe and successful journey to the frozen south.
