Weather Briefing

MVFR

Juneau International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 3,000 feet and 3 SM visibility.

Wind Analysis

Winds are from the southeast (130°) at 13 knots. Runway 08/26 is favored with a 8-knot headwind and 10-knot crosswind component.

Visibility & Ceiling

Visibility is 3 SM, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 2000 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 10°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Rain, Mist, Light Rain, Light Showers Rain. Temporary VFR conditions are forecast with Light Rain between 18:00Z and 22:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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 Juneau International Airport

Overview

Juneau International Airport serves as the primary airport for Alaska's state capital, situated in a challenging coastal environment. Located at an elevation of 21 feet MSL, the airport supports both land and water-based aircraft operations with its dual runway configuration. The airport handles a mix of commercial, private, and maritime aviation traffic in the Southeast Alaska region.

Flying Conditions

Pilots can expect variable weather conditions with significant visual flight rule (VFR) limitations. Historical data shows VFR conditions occur 68.5% of the time, with marginal VFR and instrument conditions accounting for 24.6% of observations. Temperature ranges from -23°C to 16°C, with an average of 0.7°C, and prevailing easterly winds averaging 9.4 knots with occasional gusts up to 31 knots.

Notable Features

The airport features two runways: a primary 8,457-foot asphalt runway (08/26) and a 4,900-foot water runway (08W/26W). Both runways demonstrate 100% favorable wind alignment with an average crosswind of only 4 knots. The surrounding terrain presents complex topographical challenges typical of Southeast Alaskan coastal environments, requiring careful navigation and situational awareness.

Approach Considerations

Visibility averages 8.5 statute miles, with occasional reduced conditions including fog (16.8% occurrence) and visibility below 3 miles in 5% of observations. September through November represent the most consistently favorable VFR months for operations. Pilots should prepare for potential weather variability and have appropriate instrument rating and equipment for the region's challenging conditions.
