Weather Briefing

MVFR

Monterrey International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,500 feet and 7 SM visibility.

Wind Analysis

Winds are from the east (100°) at 5 knots. Runway 12/30 is favored with a 5-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is 7 SM. The ceiling is 1500 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 25°C (77°F) with a dewpoint of 22°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. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: Haze, Light Thunderstorm Rain. Temporary MVFR conditions are forecast with Haze between 13:00Z and 16:00Z. There is a 40% probability of MVFR conditions with Light Thunderstorm Rain between 21:00Z and 01:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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.

About Monterrey International Airport

Overview

Monterrey International Airport serves as a critical aviation hub in northeastern Mexico, located in the metropolitan area of Monterrey, Nuevo Leon. Situated at an elevation of 1278 ft mean sea level, the airport handles significant commercial and cargo traffic for the region's industrial center. Its strategic location supports transportation needs for one of Mexico's most economically important metropolitan areas.

Flying Conditions

The airport's elevation at 1278 ft MSL contributes to moderate atmospheric conditions typical of northern Mexican terrain. Pilots should anticipate potential thermal variations due to the region's semi-arid climate, which can impact aircraft performance, particularly during summer months. The airport's two substantial runways (12/30 at 9843 ft and 16/34 at 5909 ft) provide operational flexibility across different wind conditions.

Notable Features

Monterrey International Airport features two asphalt runways with significant lengths, enabling operations for a wide range of aircraft types. The airport's geographical coordinates at 25.778521, -100.106989 place it in a region characterized by surrounding mountainous terrain, which may introduce specific wind and approach considerations. Pilots should be prepared for potential terrain-influenced wind patterns and visibility variations.

Approach Considerations

With runways oriented at 12/30 and 16/34, the airport offers multiple approach options depending on prevailing wind conditions. The longer 12/30 runway at 9843 ft provides substantial landing and takeoff capabilities for larger aircraft. Approach planning should consider the airport's elevation and potential thermal effects on aircraft performance, particularly during warmer periods.
