Weather Briefing

VFR

Miramar Marine Corps Air Station - Mitscher Field is currently reporting visual flight rules (VFR) conditions with scattered clouds at 2,400 feet and 10 SM visibility.

Wind Analysis

Winds are from the east (90°) at 3 knots.

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: scattered at 2,400 ft.

Temperature & Moisture

Temperature is 14°C (57°F) with a dewpoint of 12°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 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Winds are forecast to reach up to 110 knots during the period. Expect variable wind speeds ranging from 5 to 110 knots.

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 Miramar Marine Corps Air Station - Mitscher Field

Miramar Marine Corps Air Station - Mitscher Field 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

Miramar Marine Corps Air Station - Mitscher Field serves as a critical military aviation facility located in San Diego, California. Situated at 477 ft MSL, the airport supports Marine Corps aviation operations with three runways, including a substantial 12,000 ft concrete runway capable of accommodating large aircraft. The station plays a key role in Marine Corps training and operational readiness on the West Coast.

Flying Conditions

Pilots can expect predominantly favorable visual flight conditions, with 67.8% of observations reporting VFR weather. The airport experiences consistent northeast winds averaging 5.6 knots, with occasional stronger gusts up to 24 knots. Temperature ranges from 2°C to 32°C, with October through December offering the most stable VFR conditions, characterized by high visibility averaging 10.4 statute miles.

Notable Features

Located near San Diego, Miramar is positioned in a coastal environment with relatively mild weather patterns. All three runways demonstrate 100% favorable wind alignment, minimizing crosswind challenges for pilots. The airport's elevation and geographical position contribute to generally stable atmospheric conditions, with only 7.8% of observations reporting instrument flight conditions.

Approach Considerations

The primary 12,000 ft runway (06L/24R) provides ample landing surface with minimal crosswind interference. Average crosswind components remain low at approximately 3.2 knots across runways, offering consistent approach opportunities. Pilots should be prepared for occasional reduced visibility, with 6.4% of observations reporting fog and 3.3% showing visibility below 3 statute miles.
