Weather Briefing

VFR

Chiayi Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 6,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the south (180°) at 3 knots.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 6000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 27°C (81°F) with a dewpoint of 25°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. 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, Light Thunderstorm Rain. Temporary MVFR conditions are forecast with Light Rain between 19:00Z and 23:00Z. Temporary IFR conditions are forecast with Light Thunderstorm Rain between 05:00Z and 10:00Z.

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 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.
