Weather Briefing

MVFR

JASDF Hamamatsu Air Base is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,900 feet and 6 km visibility.

Wind Analysis

Winds are from the east-northeast (60°) 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 2900 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 21°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. Expected weather includes: Rain, Mist. Temporary IFR conditions are forecast between 09:00Z and 18:00Z. Temporary IFR conditions are forecast with Rain, Mist between 18:00Z 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 JASDF Hamamatsu Air Base

JASDF Hamamatsu 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

JASDF Hamamatsu Air Base is a medium-sized military airport located in Hamamatsu, Japan, serving the Japan Air Self-Defense Force (JASDF). Situated at 150 feet above mean sea level, the base is positioned at coordinates 34.750198, 137.703003, providing strategic aerial capabilities in the central region of Japan.

Flying Conditions

The airport's elevation of 150 ft MSL suggests a relatively low-altitude environment with potentially moderate atmospheric conditions. Pilots should anticipate typical coastal maritime influences given the airport's geographic location, which can introduce variable wind patterns and potential visibility challenges.

Notable Features

The primary runway 09/27 measures 8,366 feet in length, constructed with concrete (CON) surface. This substantial runway length provides flexibility for various aircraft types and operational requirements, accommodating both military and potential alternate civilian aviation needs.

Approach Considerations

Given the runway's 09/27 orientation, pilots should be prepared for approaches from either easterly (09) or westerly (27) directions depending on prevailing wind conditions. The concrete runway surface offers reliable traction and stability for aircraft operations, with sufficient length to support a wide range of aircraft landing and takeoff profiles.
