Weather Briefing

IFR

Miramar Marine Corps Air Station - Mitscher Field is currently reporting instrument flight rules (IFR) conditions with overcast skies at 900 feet and 8 SM visibility.

Wind Analysis

Winds are from the southwest (230°) at 3 knots.

Visibility & Ceiling

Visibility is 8 SM. The ceiling is 900 feet AGL (overcast). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is 21°C (70°F) with a dewpoint of 19°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. Temporary MVFR conditions are forecast between 02:00Z and 08:00Z.

Pilot Recommendations

An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours.

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.
