Weather Briefing

VFR

San Antonio International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 1,500 feet and 10 SM visibility.

Wind Analysis

Winds are from the southeast (140°) at 7 knots. Runway 13L/31R is favored with a 7-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: scattered at 1,500 ft, scattered at 25,000 ft.

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 27 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

Conditions are favorable for visual flight. 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.
