Weather Briefing

MVFR

JASDF Matsushima Air Base is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west (270°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 1200 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 12°C (54°F) with a dewpoint of 9°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. Temporary IFR conditions are forecast between 19:00Z and 22:00Z.

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 Matsushima Air Base

JASDF Matsushima 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 Matsushima Air Base is a military airfield located in Ishinomaki, Japan, serving as a strategic base for the Japan Air Self-Defense Force (JASDF). Situated at a low elevation of 7 feet mean sea level, the base provides critical aviation infrastructure in the northeastern region of Honshu Island. Its geographical position and substantial runway infrastructure make it a key facility for military aviation operations.

Flying Conditions

The base's coastal location near the Pacific Ocean likely introduces variable maritime weather conditions that pilots must carefully consider. With two concrete runways - a primary 8,860-foot runway (07/25) and a secondary 4,920-foot runway (15/33) - the airport offers multiple operational configurations to accommodate different wind and weather scenarios. Pilots should anticipate potential marine layer formations and wind shifts typical of coastal Japanese environments.

Notable Features

Matsushima Air Base is characterized by its relatively flat terrain and low elevation, which provides straightforward approach and departure profiles. The base's dual-runway configuration allows for flexible operational planning, with runways oriented to handle winds from different quadrants. Its proximity to the Pacific coastline means potential for rapidly changing meteorological conditions that require constant situational awareness.

Approach Considerations

Given the base's geographical orientation, runway 07/25 and 15/33 provide options for landing based on prevailing wind conditions. The substantial length of the primary runway (8,860 feet) offers excellent landing and takeoff capabilities for various aircraft types. Pilots should conduct thorough pre-flight weather briefings to understand current wind vectors and potential maritime weather influences specific to this coastal region.
