Weather Briefing

VFR

Air Force Colonel Alfredo Mendivil Duarte Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 8,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 8000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 11°C (52°F) with a dewpoint of 8°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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: Rain. Temporary MVFR conditions are forecast between 18:00Z and 21:00Z. Temporary IFR conditions are forecast with Rain between 10:00Z and 14:00Z.

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.

The airport experiences predominantly favorable VFR conditions, with 96.5% of observations showing visual flight rules. Winds typically blow from the northeast at an average of 4.8 knots, with occasional strong gusts up to 46 knots. Temperature variations are moderate, ranging from 9°C to 29°C with an average of 19.3°C, providing relatively stable flying conditions throughout the year.

Notable Features

Located at high altitude with coordinates -13.154800, -74.204399, the airport presents unique challenges for aircraft performance and operations. The single runway 02/20 is 9,186 feet long with an asphalt surface, designed to accommodate the demands of high-elevation airport operations. Pilots must carefully consider density altitude effects due to the significant elevation of 8,917 feet MSL.

Approach Considerations
