Weather Briefing

VFR

Plan De Guadalupe International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 10,000 feet and 12 SM visibility. Note: This observation is 6.7 hours old and conditions may have changed.

Wind Analysis

Winds are from the north (360°) at 3 knots.

Visibility & Ceiling

Visibility is 12 SM. No ceiling exists. Cloud layers reported: scattered at 10,000 ft, scattered at 20,000 ft.

Temperature & Moisture

Temperature is 23°C (73°F) with a dewpoint of 19°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods. 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: Haze. Temporary MVFR conditions are forecast with Haze between 11:00Z and 15:00Z.

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.

About Plan De Guadalupe International Airport

Overview

Plan De Guadalupe International Airport serves the Saltillo metropolitan area in northeastern Mexico, located at an elevation of 4,778 feet mean sea level. As a medium-sized airport with two asphalted runways, it provides critical aviation infrastructure for regional commercial and general aviation operations in the Coahuila state.

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.
