About Brown Field Municipal Airport

Overview

Brown Field Municipal Airport serves the San Diego metropolitan area as a medium-sized airport located near the US-Mexico border. Situated at an elevation of 526 feet MSL, the airport provides critical aviation infrastructure for the region, with two substantial runways offering flexible operational capabilities.

Flying Conditions

Pilots can expect predominantly VFR conditions 65.4% of the time, with marginal VFR and IFR conditions occurring less frequently. The airport experiences consistent western winds averaging 5.6 knots, with occasional stronger gusts up to 23 knots, and calm conditions present 33.9% of the time. Temperature variations range from 3°C to 32°C, with November, December, and October offering the most favorable VFR flying conditions.

Notable Features

The airport features two runways with different surface compositions: Runway 08L/26R is a primary runway with a PEM (presumed concrete/cement) surface measuring 7,972 feet, while Runway 08R/26L is an auxiliary 3,180-foot ASP (asphalt) runway. Both runways demonstrate 100% favorable wind alignment and an average crosswind of 3.1 knots, providing consistent and predictable wind conditions for pilots.

Approach Considerations

Visibility averages 8 statute miles, with instances of reduced visibility below 3 miles occurring in 6.3% of observations and fog present in 8.3% of cases. Pilots should be prepared for potential visual limitations, particularly during periods of reduced meteorological conditions. The consistent western wind pattern suggests Runways 08L/26R and 08R/26L will typically offer favorable wind conditions for approaches and departures.
