Weather Briefing

LIFR

JASDF Hamamatsu Air Base is currently reporting low IFR (LIFR) conditions with clear skies and 1.6 km visibility.

Wind Analysis

Winds are from the north-northwest (330°) at 4 knots.

Visibility & Ceiling

Visibility is severely reduced to 1.6 km, likely due to fog, mist, or precipitation. Special VFR or an IFR clearance may be required. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 16°C (61°F) with a dewpoint of 12°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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: Light Rain, Mist, Showers Rain, Mist. Temporary IFR conditions are forecast with Light Rain, Mist between 00:00Z and 03:00Z. Temporary LIFR conditions are forecast with Showers Rain, Mist between 03:00Z and 12:00Z. Temporary LIFR conditions are forecast with Light Rain, Mist between 12:00Z and 15:00Z.

Pilot Recommendations

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums.

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.
