Weather Briefing

MVFR

Kushiro Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,400 feet and 10 miles or greater visibility. Note: This observation is 1.1 hours old and conditions may have changed.

Wind Analysis

Winds are from the southwest (230°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1400 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 11°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. 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: Mist. Temporary LIFR conditions are forecast with Mist between 12:00Z and 15:00Z. Temporary LIFR conditions are forecast with Mist between 15:00Z and 22:00Z. Temporary IFR conditions are forecast with Mist between 22:00Z 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 Kushiro Airport

Overview

Kushiro Airport serves the eastern Hokkaido region of Japan, located at an elevation of 327 feet MSL near the city of Kushiro. As a medium-sized airport with a single runway (17/35) measuring 8,202 feet, it provides essential transportation infrastructure for this relatively remote area of northern Japan.

Flying Conditions

Weather conditions at Kushiro Airport demonstrate significant variability, with Visual Flight Rules (VFR) conditions prevailing 77% of the time. The airport experiences a broad temperature range from -14°C to 28°C, with an average of 4.4°C. Wind patterns are predominantly westerly at 7.2 knots, with occasional gusts up to 33 knots, and minimal periods of calm conditions.

Notable Features

The airport's location in Hokkaido presents unique geographic considerations for pilots, with potential for challenging maritime and mountainous influences. The single runway (17/35) is aligned to take advantage of prevailing westerly winds, with an average crosswind of just 4.2 knots. Visibility is generally excellent, averaging 10 statute miles with minimal instances of restricted visibility.

Approach Considerations

Pilots should note that November, January, and September offer the most consistently favorable VFR conditions. The runway demonstrates 100% wind favorability, meaning crosswind components are typically manageable. While instrument conditions occur in approximately 16.1% of observations (MVFR, IFR, and LIFR combined), the airport maintains relatively predictable approach characteristics.
