Weather Briefing

VFR

JASDF Hamamatsu Air Base is currently reporting visual flight rules (VFR) conditions with overcast skies at 14,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the south (190°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 14000 feet AGL (overcast), well above standard VFR minimums.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 14°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Rain.

Pilot Recommendations

Conditions are favorable for visual flight. 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.
