Weather Briefing
MVFRPonciano Arriaga International Airport is currently reporting marginal VFR (MVFR) conditions with clear skies and 5 SM visibility.
Wind Analysis
Winds are calm, presenting no crosswind concerns for any runway.
Visibility & Ceiling
Visibility is 5 SM. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 13°C (55°F) with a dewpoint of 12°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. Conditions are expected to remain VFR throughout the forecast period.
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 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.
