Weather Briefing

VFR

Plan De Guadalupe International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 20,000 feet and 12 SM visibility.

Wind Analysis

Winds are from the north-northeast (20°) at 13 knots. Runway 03/21 is favored with a 13-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 12 SM. The ceiling is 20000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 29°C (84°F) with a dewpoint of 16°C, indicating relatively dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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: Thunderstorm Rain. Temporary MVFR conditions are forecast with Thunderstorm Rain between 19:00Z and 23:00Z.

Pilot Recommendations

Conditions are favorable for visual flight. 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.

Flying Conditions

The airport experiences predominantly visual flight rules (VFR) conditions, with 81.6% of observations supporting clear weather operations. Wind patterns are characterized by northerly prevailing winds averaging 8.3 knots, though gusts up to 60 knots can occur, with calm conditions present 23.7% of the time. Temperature ranges from 0°C to 33°C, with an average of 19.7°C, creating generally stable flying conditions.

Notable Features

Situated at a significant elevation of 4,778 feet MSL, the airport presents density altitude considerations for aircraft performance. The airport features two runways: runway 03/21 at 3,471 feet and runway 17/35 at 9,506 feet, providing operational flexibility for various aircraft types. Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind components of 3.4 and 3.3 knots respectively.

Approach Considerations

September, October, and January represent the most consistent VFR months, offering optimal flying conditions. Visibility averages 8.8 statute miles, with only 2.5% of observations showing conditions below 3 statute miles. Pilots should be prepared for occasional fog events, which occur approximately 6% of the time, potentially impacting approach and landing operations.
