Weather Briefing
MVFRNorth Island Naval Air Station-Halsey Field is currently reporting marginal VFR (MVFR) conditions with overcast skies at 1,800 feet and 10 SM visibility. Note: This observation is 1.6 hours old and conditions may have changed.
Wind Analysis
Winds are from the south-southeast (160°) at 8 knots. Runway 18/36 is favored with a 8-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1800 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 17°C (63°F) with a dewpoint of 13°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 24 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Temporary VFR conditions are forecast between 19:00Z and 01:00Z.
Pilot Recommendations
VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About North Island Naval Air Station-Halsey Field
North Island Naval Air Station-Halsey 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
North Island Naval Air Station-Halsey Field is a medium-sized airport located in San Diego, California, serving naval aviation operations. Situated at 26 feet above mean sea level, the base is strategically positioned on the western edge of the continental United States. The airport features two substantial runways capable of supporting various military and potential civilian aircraft operations.
Flying Conditions
Weather conditions at KNZY are predominantly favorable for flying, with Visual Flight Rules (VFR) conditions present 65.9% of the time. Pilots can expect northwest winds averaging 6.4 knots, with occasional stronger gusts up to 30 knots. Temperature ranges from 7°C to 34°C, with best VFR conditions typically occurring in October, November, and January.
Notable Features
Both runways (11/29 and 18/36) offer excellent wind alignment, with 100% favorable wind coverage and minimal average crosswind conditions (3.7-3.8 knots). The airport's proximity to the Pacific Ocean influences its microclimate, with occasional fog events affecting 4% of observations and visibility dropping below 3 statute miles in 2.6% of recorded conditions.
Approach Considerations
Runway selection should consider the prevailing northwest winds, which dominate the local wind pattern. Both 7,500-foot (11/29) and 8,000-foot (18/36) runways provide substantial landing options with consistent wind characteristics. Pilots should be prepared for potential marine layer influences and verify current weather conditions before approach, given the airport's coastal location.
