Weather Briefing

VFR

Juneau International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 4,900 feet and 10 SM visibility.

Wind Analysis

Winds are from the east (100°) at 4 knots.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 4900 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 6°C (43°F) with a dewpoint of 5°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 Rain, Mist, Light Drizzle, Mist. Temporary MVFR conditions are forecast with Light Rain, Mist between 08:00Z and 10:00Z. 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 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.
