Weather Statistics - NZWD
2,091 observations | Oct 2025 - Feb 2026Flight Rules Distribution
Williams Field Skiway typically experiences VFR conditions 74% of the time, though instrument-rated pilots will find IFR weather present approximately 17.4% of observations. Prevailing winds are from the NE averaging 8 knots, with gusts recorded up to 120 knots. Temperature extremes range from -28°C to 3°C, reflecting significant seasonal variation. Fog is a notable factor, occurring in approximately 18% of observations, with visibility below 3 SM in 0% of reports. The best months for VFR flying are October, February, November.

About Williams Field Skiway
Overview
Williams Field Skiway serves the critical aviation needs of McMurdo Station in Antarctica, functioning as a key transportation link for scientific and logistical operations. Located at 68 feet above mean sea level, this medium airport provides essential air access to the Antarctic continent, supporting research and support missions in one of the world's most extreme environments.
Flying Conditions
Antarctic flying conditions at Williams Field are characterized by extreme cold and persistent snow coverage, reflected in the airport's snow-based (SNO) runway designations. The two parallel runways (07/25 and 15/33) are each 10,000 feet long, providing substantial landing and takeoff options for aircraft operating in this challenging polar environment.
Notable Features
The airport's geographic coordinates at -77.867401, 167.057007 place it in a unique polar landscape with significant terrain considerations. The relatively low elevation of 68 feet MSL belies the complex environmental challenges of operating aircraft in Antarctica, where surface conditions can change rapidly and visibility can be severely limited by polar weather patterns.
Approach Considerations
With two 10,000-foot runways oriented in different directions (07/25 and 15/33), pilots have flexibility in approach based on prevailing wind conditions. The snow surface runways require specialized equipment and techniques, with careful consideration of surface conditions and aircraft compatibility for safe operations in this extreme Antarctic environment.
