Weather Briefing

VFR

JMSDF Kanoya Air Base is currently reporting visual flight rules (VFR) conditions with scattered clouds at 3,500 feet and 10 miles or greater visibility. Note: This observation is 680.2 hours old and conditions may have changed.

Wind Analysis

Winds are from the southwest (220°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. No ceiling exists. Cloud layers reported: few at 2,000 ft, scattered at 3,500 ft.

Temperature & Moisture

Temperature is 15°C (59°F) with a dewpoint of 13°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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.

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

About JMSDF Kanoya Air Base

JMSDF Kanoya 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

JMSDF Kanoya Air Base is a medium-sized airport located in southern Japan, serving the Japan Maritime Self-Defense Force (JMSDF) operations. Situated at an elevation of 214 feet MSL near Kanoya City, the base features two concrete runways capable of supporting maritime patrol and naval aviation activities. Its strategic location in Kyushu provides critical maritime surveillance capabilities for the region.

Flying Conditions

The airport experiences predominantly VFR conditions, with 49.2% of observations indicating good visual flight rules. Westerly winds dominate at 270°, averaging 8.7 knots with occasional gusts up to 24 knots. Temperature ranges from 1°C to 32°C, with an average of 18.3°C, offering relatively stable flying conditions throughout the year. January, November, and December statistically provide the best VFR weather conditions.

Notable Features

Both runways (08L/26R and 08R/26L) offer 100% favorable wind alignment, minimizing crosswind challenges for pilots. The longer runway (08R/26L) extends 7,382 feet, providing ample length for maritime patrol and naval aircraft operations. The airport's location in southern Japan means terrain and local geographical features may influence local wind patterns and approach conditions.

Approach Considerations

With consistent wind patterns and high visibility (average 10 statute miles), approaches to either runway present predictable conditions. Average crosswind components remain low at 4.3 knots for both runways, facilitating straightforward landings. Pilots should anticipate potential maritime weather influences typical of a coastal Japanese location, with minimal fog occurrence (3.5% of observations) and consistently good visibility.

Data Sources & Accuracy: Airport information sourced from OurAirports.com, a collaborative database of worldwide airport data. Weather data from official aviation weather services including NOAA Aviation Weather Center and international METAR/TAF providers. Information is updated regularly but pilots should always verify current conditions and NOTAMs through official channels before flight operations.
