Weather Briefing

MVFR

Chiayi Airport is currently reporting marginal VFR (MVFR) conditions with scattered clouds at 2,500 feet and 8 km visibility.

Wind Analysis

Winds are from the east (100°) at 3 knots.

Visibility & Ceiling

Visibility is 8 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. No ceiling exists. Cloud layers reported: few at 1,200 ft, scattered at 2,500 ft.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 23°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 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Light Rain, Light Rain, Mist. Temporary VFR conditions are forecast between 19:00Z and 00:00Z. Temporary MVFR conditions are forecast with Light Rain between 06:00Z and 11:00Z.

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.

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

About Chiayi Airport

Overview

Chiayi Airport serves as a medium-sized airport located in Shuishang, Taiwan, positioned at coordinates 23.462577, 120.390544. The airport sits at an elevation of 85 feet mean sea level (MSL) and provides essential aviation infrastructure for the region. Its three runways offer substantial capacity for various aircraft operations.

Flying Conditions

Situated in central Taiwan, Chiayi Airport experiences typical subtropical climate conditions that can produce variable weather patterns. The airport's moderate elevation at 85 ft MSL suggests relatively stable atmospheric conditions, though pilots should anticipate potential seasonal humidity and precipitation variations. Temperature and wind characteristics will likely influence runway selection and approach strategies.

Notable Features

The airport features three distinct runways: an unspecified 18/36 runway, a 5,307-foot asphalted 18L/36R runway, and a substantial 10,007-foot concrete 18R/36L runway. This diverse runway configuration provides operational flexibility for different aircraft types and weights. The substantial length of the 18R/36L runway particularly accommodates larger aircraft and potentially supports complex operational requirements.

Approach Considerations

Runway orientation suggests north-south approaches with multiple parallel runway options. Pilots should carefully evaluate runway lengths and surface types when planning arrivals and departures. The concrete 10,007-foot runway offers the most extensive operational capability and likely represents the primary approach and landing surface for most aircraft movements.
