Weather Briefing

MVFR

Ponciano Arriaga International Airport is currently reporting marginal VFR (MVFR) conditions with scattered clouds at 8,000 feet and 5 SM visibility. Note: This observation is 1.4 hours old and conditions may have changed.

Wind Analysis

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

Visibility & Ceiling

Visibility is 5 SM. No ceiling exists. Cloud layers reported: scattered at 8,000 ft, scattered at 23,000 ft.

Temperature & Moisture

Temperature is 14°C (57°F) with a dewpoint of 13°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. 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: Haze, Mist, Haze, Thunderstorm Rain. Temporary IFR conditions are forecast with Mist, Haze between 11:00Z and 15:00Z. Temporary MVFR conditions are forecast with 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. 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 Ponciano Arriaga International Airport

Overview

Ponciano Arriaga International Airport serves San Luis Potosí in central Mexico, providing medium-sized airport capabilities at a significant elevation of 6,035 feet MSL. The airport supports regional and commercial aviation with two asphalted runways capable of handling diverse aircraft operations. Its strategic location offers critical transportation infrastructure for the San Luis Potosí region.

Flying Conditions

Weather conditions at MMSP are predominantly visual flight rules (VFR), with 68.9% of observations supporting clear flying conditions. Pilots can expect primarily easterly winds averaging 6.4 knots, with occasional gusts up to 22 knots. Temperature ranges from 0°C to 29°C, with an average of 15.9°C, and visibility typically excellent at 7.7 statute miles, though fog can occasionally reduce visibility to below 3 miles.

Notable Features

The airport's high elevation at 6,035 feet MSL presents performance considerations for aircraft operations, particularly during warmer temperatures. Both runways (04/22 and 14/32) offer consistent wind alignment, with 100% favorable wind conditions. The longer runway 14/32 provides 9,867 feet of paved surface, accommodating larger aircraft and offering flexibility for diverse operational requirements.

Approach Considerations

Pilots should anticipate predominantly easterly winds when planning approaches, with an average crosswind of 3.9-4.5 knots across both runways. November through January represent the most consistent VFR months, offering the most predictable flying conditions. The relatively low percentage of IFR (4.2%) and LIFR (1.5%) conditions suggests generally reliable visual meteorological conditions throughout the year.
