Weather Briefing

MVFR

JGSDF Kisarazu Airfield is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,500 feet and 10 miles or greater visibility. Note: This observation is 651.1 hours old and conditions may have changed.

Wind Analysis

Winds are from the north-northeast (20°) at 12 knots. Runway 02/20 is favored with a 12-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1500 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 13°C (55°F) with a dewpoint of 10°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About JGSDF Kisarazu Airfield

Overview

JGSDF Kisarazu Airfield is a medium-sized airport located in Kisarazu, Japan, serving primarily military operations. Situated at an elevation of 10 feet mean sea level, the airfield is positioned at coordinates 35.398300, 139.910004. The airport supports Japan Ground Self-Defense Force (JGSDF) aviation activities in the greater Tokyo regional area.

Flying Conditions

The airfield's low elevation of 10 ft MSL indicates a coastal plain environment with minimal terrain complexity. Being located near Tokyo Bay, pilots should anticipate potential maritime weather influences including variable wind conditions and potential marine layer formations. Seasonal weather patterns typical of the Kanto region will impact local atmospheric conditions.

Notable Features

Kisarazu Airfield features a single runway (02/20) with an asphalt surface measuring 6,004 feet in length. The runway orientation suggests potential crosswind scenarios, particularly given the coastal proximity. The airport's strategic location near Tokyo provides critical infrastructure for military aviation operations in the region.

Approach Considerations

Runway 02/20's substantial 6,004-foot length accommodates a range of aircraft types typical to military operations. Pilots should prepare for potential wind variations given the coastal environment and be aware of the runway's alignment. Standard military approach procedures and local air traffic control protocols will govern arrival and departure sequences.
