Weather Briefing

VFR

Gustavus Airport is currently reporting visual flight rules (VFR) conditions with overcast skies at 4,600 feet and 10 SM visibility.

Wind Analysis

Winds are from the southwest (220°) at 3 knots.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 4600 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 5°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. Conditions are expected to remain VFR throughout the forecast period. Expected weather includes: Light Showers Rain.

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.

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.
