Weather Briefing

IFR

Taipei Songshan Airport is currently reporting instrument flight rules (IFR) conditions with broken clouds at 1,600 feet and 3.5 km visibility.

Wind Analysis

Winds are from the east (100°) at 12 knots. Runway 10/28 is favored with a 12-knot headwind and 0-knot crosswind component.

Visibility & Ceiling

Visibility is reduced to 3.5 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is 1600 feet AGL (broken), placing conditions in the MVFR category. Caution: towering cumulus clouds reported at 2,000 ft AGL, indicating convective activity in the area.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 20°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Rain, Showers Rain, Light Showers Rain. Temporary MVFR conditions are forecast with Light Rain between 06:00Z and 12:00Z. Temporary IFR conditions are forecast with Showers Rain between 12:00Z and 18:00Z. Temporary MVFR conditions are forecast with Light Showers Rain between 18:00Z and 00:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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.
