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.
