Weather Briefing

VFR

Gustavus Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 5,500 feet and 10 SM visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 5500 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 6°C (43°F) with a dewpoint of 4°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers Rain, Light Drizzle, Mist. Temporary MVFR conditions are forecast with Light Showers Rain between 07:00Z and 08:00Z. There is a 30% probability of LIFR conditions with Light Drizzle, Mist between 15:00Z and 18:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Gustavus Airport

Overview

Gustavus Airport serves the small community of Gustavus in southeastern Alaska, located near Glacier Bay National Park. The medium-sized airport provides critical transportation infrastructure in a remote coastal region, supporting local and regional aviation needs. Its strategic location and two substantial runways make it an important aviation hub for the area.

Flying Conditions

Weather at Gustavus Airport demonstrates significant variability, with Visual Flight Rules (VFR) conditions prevalent 55.7% of the time. Marginal VFR and Instrument Flight Rules conditions occur frequently, with IFR and LIFR conditions accounting for 19% of observations. Pilots should anticipate predominantly southeastern winds averaging 7.2 knots, with temperatures ranging from -14°C to 17°C and average visibility around 8.7 statute miles.

Notable Features

Situated at a low elevation of 35 feet mean sea level, Gustavus Airport features two asphalt runways with substantial lengths. Runway 02/20 provides a 3,010-foot surface, while Runway 11/29 offers an extended 6,720-foot option. Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind conditions of 6.2 knots and 3.3 knots respectively.

Approach Considerations

Optimal flying conditions occur during September, October, and November, with the most consistent weather patterns. Calm wind conditions are observed 31.4% of the time, providing predictable approach opportunities. Pilots should be prepared for potential reduced visibility, as 5.1% of observations report visibility below 3 statute miles, and 4.4% of observations indicate fog presence.
