Weather Briefing
MVFRIbaraki Airport / JASDF Hyakuri Air Base is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,200 feet and 6 km visibility.
Wind Analysis
Winds are from the north (350°) at 4 knots.
Visibility & Ceiling
Visibility is 6 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 1200 feet AGL (broken), placing conditions in the MVFR category.
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 IFR conditions are forecast with Mist between 15:00Z and 21:00Z.
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 Ibaraki Airport / JASDF Hyakuri Air Base
Ibaraki Airport / JASDF Hyakuri Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the JP AIP for current access procedures and restrictions.
Overview
Ibaraki Airport, located in Omitama, Japan, serves as both a civilian and military airfield hosting Japan Air Self-Defense Force operations. Situated at 105 feet mean sea level, the airport provides strategic aviation infrastructure in the Ibaraki Prefecture region. The airport features a substantial 8,860-foot concrete runway oriented 03/21, supporting diverse aircraft operations.
Flying Conditions
Weather conditions at Ibaraki Airport demonstrate predominantly favorable VFR flying conditions, with 73.6% of observations reporting visual meteorological conditions. Temperatures range widely from -7°C to 34°C, with an average of 11.9°C, indicating significant seasonal variation. Wind patterns are consistently from the north, averaging 6.1 knots with occasional gusts up to 27 knots, and experiencing calm conditions only 3% of the time.
Notable Features
The airport's elevation and geographic positioning contribute to relatively stable meteorological environments, with excellent visibility averaging 10 statute miles. Pilots can expect minimal low visibility challenges, with fog present in only 4.4% of observations. The runway's orientation and length provide flexibility for multiple aircraft types and operational requirements.
Approach Considerations
Runway 03/21 demonstrates highly favorable wind conditions, with 100% wind compatibility and minimal average crosswind of 3 knots. January, November, and December represent the most consistent VFR months for flight operations. Pilots should anticipate predictable wind patterns and generally clear approach conditions based on historical meteorological data.
