Weather Briefing

VFR

Randolph Air Force Base is currently reporting visual flight rules (VFR) conditions with clear skies and 10 SM visibility. Note: This observation is 2.9 hours old and conditions may have changed.

Wind Analysis

Winds are from the south-southeast (150°) at 7 knots. Runway 14L/32R is favored with a 7-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. Skies are clear with unlimited ceiling.

Temperature & Moisture

Temperature is 24°C (75°F) with a dewpoint of 21°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 30 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: Mist. Temporary MVFR conditions are forecast between 16:00Z and 18:00Z.

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 Randolph Air Force Base

Randolph Air Force Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the US AIP for current access procedures and restrictions.

Overview

Randolph Air Force Base (KRND) is located in Universal City, serving as a strategic military aviation facility near San Antonio, Texas. The base features two substantial concrete and pavement runways, each approximately 8,350 feet long, capable of supporting a wide range of military aircraft operations. Its strategic location and substantial runway infrastructure make it a significant Air Force installation in the southwestern United States.

Flying Conditions

Pilots can expect predominantly favorable flying conditions at Randolph AFB, with Visual Flight Rules (VFR) conditions occurring 62.1% of the time. The base experiences a moderate temperature range from -1°C to 38°C, with an average temperature of 19.7°C. Wind patterns are predominantly from the south at an average of 6.8 knots, with calm conditions present 13.6% of the time, providing generally stable atmospheric conditions for aviation.

Notable Features

Situated at an elevation of 761 feet mean sea level, Randolph AFB offers relatively flat terrain typical of the Texas landscape. Both primary runways (14L/32R and 14R/32L) demonstrate identical wind characteristics, with 100% favorable wind conditions and an average crosswind of 4.3 knots. The base's consistent wind profile and substantial runway lengths provide flexibility for various aircraft operations.

Approach Considerations

September, October, and January represent the most consistent VFR months for operations at Randolph AFB. With an average visibility of 9.4 statute miles and minimal low visibility events (fog occurs only 1.5% of the time), pilots can generally expect clear approach conditions. The symmetrical runway configuration and prevailing southern winds facilitate predictable approach and landing scenarios for incoming aircraft.
