Weather Briefing
VFRNorth Island Naval Air Station-Halsey Field is currently reporting visual flight rules (VFR) conditions with clear skies.
Wind Analysis
Winds are from the northeast (40°) at 8 knots. Runway 36 is favored with a 6-knot headwind and 5-knot crosswind component.
Visibility & Ceiling
Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is 19°C (66°F) with a dewpoint of 16°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
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.
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.
