Weather Briefing

VFR

Naha Airport / JASDF Naha Air Base is currently reporting visual flight rules (VFR) conditions with broken clouds at 3,500 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the north-northwest (330°) at 18 knots. Runway 36 is favored with a 16-knot headwind and 9-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 3500 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 19°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.

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 Naha Airport / JASDF Naha Air Base

Naha Airport / JASDF Naha 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

Naha Airport serves as a critical aviation hub located in Okinawa, Japan, functioning as both a civilian international airport and a Japan Air Self-Defense Force (JASDF) air base. Situated at a low elevation of 12 feet MSL, the airport provides essential air connectivity for the Okinawa prefecture and supports military operational requirements in the region.

Flying Conditions

The airport experiences predominantly excellent Visual Flight Rules (VFR) conditions, with 95% of observations indicating clear weather suitable for visual flying. Temperature ranges from 11°C to 34°C, with an average of 23.4°C, providing stable thermal conditions. Wind patterns are consistently from the northeast at an average of 11.1 knots, with maximum gusts up to 32 knots.

Notable Features

Naha Airport features two substantial asphalt runways: 18L/36R at 9,840 feet and 18R/36L at 8,858 feet. Both runways demonstrate 100% favorable wind conditions with an average crosswind of just 5.6 knots, indicating highly predictable and manageable wind characteristics. The airport's geographical location in the Ryukyu Islands provides unique meteorological conditions typical of subtropical maritime environments.

Approach Considerations

Pilots can expect optimal flying conditions during January, September, and October, which statistically offer the best VFR weather. The consistent northeast wind and low elevation make approaches relatively straightforward, with excellent average visibility of 10 statute miles. Both runways are equally viable for landing, with negligible crosswind interference.
