Weather Briefing

IFR

Kushiro Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 1,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the southwest (220°) at 4 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 600 feet AGL (broken). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 13°C (55°F) with a dewpoint of 12°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 18:00Z and 22:00Z. Temporary IFR conditions are forecast with Mist between 22:00Z and 00:00Z. Temporary IFR conditions are forecast between 00:00Z and 03:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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.
