Weather Briefing
MVFRSan Antonio International Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 3,300 feet and 10 SM visibility.
Wind Analysis
Winds are from the south (170°) at 11 knots with gusts to 18 knots. Runway 13L/31R is favored with a 8-knot headwind and 7-knot crosswind component (gusting to 12 knots crosswind).
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1100 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 25°C (77°F) with a dewpoint of 23°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 30 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Temporary IFR conditions are forecast between 09:00Z and 13:00Z.
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 San Antonio International Airport
Overview
San Antonio International Airport serves as a major commercial and cargo aviation hub in south-central Texas. Located at 29.533701, -98.469803, the airport sits at an elevation of 809 feet above mean sea level, providing strategic connectivity for the San Antonio metropolitan region. The airport supports diverse aviation operations with three substantial runways capable of handling large commercial aircraft.
Flying Conditions
San Antonio's airport environment experiences typical south Texas climate conditions with potential for significant thermal variations. The airport's elevation and geographic position can generate localized wind shifts and thermal turbulence, particularly during summer months. Pilots should anticipate potential crosswind challenges, especially on the shorter 13L/31R runway with its 5,519-foot asphalt surface.
Notable Features
The airport features three runways with substantial length: two concrete runways at 8,505 and 8,502 feet, and one asphalt runway at 5,519 feet. Its mid-latitude location means terrain surrounding the airport is generally flat with minimal elevation changes, providing relatively straightforward visual and instrument approach conditions. The three-runway configuration offers operational flexibility for different wind conditions and traffic volumes.
Approach Considerations
Runway 04/22 and 13R/31L offer the longest concrete surfaces, providing optimal landing options for larger commercial aircraft. Prevailing winds in the region typically favor east-west and northwest-southeast approach vectors. Pilots should carefully evaluate current wind conditions to select the most appropriate runway, considering crosswind components and available runway length.
