Weather Briefing

MVFR

Jacksonville Naval Air Station (Towers Field) is currently reporting marginal VFR (MVFR) conditions with broken clouds 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 (180°) at 7 knots. Runway 14/32 is favored with a 5-knot headwind and 4-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 1800 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 20°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 20 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers Rain. Temporary MVFR conditions are forecast between 11:00Z and 15:00Z. Temporary LIFR conditions are forecast with Light Showers Rain between 00:00Z and 03:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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 Jacksonville Naval Air Station (Towers Field)

Jacksonville Naval Air Station (Towers 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

Jacksonville Naval Air Station (Towers Field) serves as a critical naval aviation facility located in Jacksonville, Florida. Situated at 21 feet above mean sea level, the base supports military aviation operations with two substantial runways capable of accommodating various aircraft types. Its strategic coastal location provides significant operational flexibility for naval aviation training and support missions.

Flying Conditions

Weather conditions at KNIP demonstrate highly favorable VFR flying environments, with 80.4% of observations reporting visual flight rules. Temperatures range from -1°C to 34°C, creating relatively stable aviation conditions throughout the year. Wind patterns predominantly originate from the north at an average of 7.8 knots, with calm conditions occurring 11.6% of the time and maximum gusts reaching 23 knots.

Notable Features

The airport features two paved runways: a longer 8,002-foot runway (10/28) and a 5,984-foot runway (14/32). Both runways demonstrate 100% favorable wind alignment, with minimal average crosswind conditions (5.7kt and 5.1kt respectively). The low elevation and coastal positioning suggest minimal terrain-related operational challenges for approaching aircraft.

Approach Considerations

Pilots should note September, October, and November represent the most consistently favorable VFR months for operations. Visibility averages 9.4 statute miles, with only 1.9% of observations showing visibility below 3 statute miles. Fog occurs in just 1.5% of observations, indicating generally clear approach conditions throughout the year.
