Weather Briefing

MVFR

Hakodate Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the east-northeast (70°) at 4 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1000 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 16°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 30 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Temporary IFR conditions are forecast between 13:00Z and 16:00Z. Temporary IFR conditions are forecast between 16:00Z and 21:00Z. Temporary IFR conditions are forecast between 21:00Z and 00:00Z.

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. 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 Hakodate Airport

Overview

Hakodate Airport serves the southern region of Hokkaido, Japan, located at an elevation of 151 feet MSL. The medium-sized airport provides critical transportation infrastructure for the Hakodate metropolitan area, supporting regional and domestic aviation operations with its single 9,842-foot asphalt runway.

Flying Conditions

Pilots can expect predominantly VFR conditions, with 74.4% of observations indicating good visual flying weather. The airport experiences a significant temperature range from -15°C to 27°C, with an average temperature of 5.9°C. Wind patterns are consistently from the northwest at an average of 8.7 knots, with occasional gusts up to 31 knots.

Notable Features

The airport's geographic location near the southern tip of Hokkaido introduces potential maritime weather influences. Terrain surrounding the airport is likely to include coastal and potentially mountainous characteristics typical of the Hokkaido region. Runway 12/30 demonstrates 100% favorable wind alignment, with an average crosswind component of just 3.8 knots.

Approach Considerations

October, November, and September represent the most stable VFR months for operations. The runway's orientation and length provide flexible approach options, with minimal reported visibility restrictions (average visibility 10 statute miles) and extremely rare fog conditions (0.1% occurrence). Pilots should anticipate northwest wind patterns during approach and departure planning.
