Weather Briefing

VFR

Jacksonville International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 25,000 feet and 10 SM visibility. Note: This observation is 1.1 hours old and conditions may have changed.

Wind Analysis

Winds are from the west (270°) at 4 knots.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 25000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 26°C (79°F) with a dewpoint of 23°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. Expected weather includes: Thunderstorm Rain. Winds are forecast to reach up to 20 knots during the period. Expect variable wind speeds ranging from 5 to 20 knots. There is a 30% probability of MVFR conditions with Thunderstorm Rain between 21:00Z and 03:00Z.

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 Jacksonville International Airport

Overview

Jacksonville International Airport serves as a primary commercial and cargo aviation hub for northeast Florida. Located in Duval County, the airport handles significant passenger and freight traffic for the Jacksonville metropolitan area. Its strategic position and substantial runway infrastructure make it a key transportation facility in the southeastern United States.

Flying Conditions

Jacksonville's coastal location produces variable weather conditions typical of subtropical maritime climates, with potential for sudden meteorological changes. The airport's relatively low elevation of 30 ft MSL means minimal terrain-induced turbulence, but proximity to the Atlantic coast can introduce marine layer conditions and occasional crosswind challenges. Pilots should anticipate potential wind shifts, particularly during seasonal transition periods.

Notable Features

The airport features two substantial concrete runways: Runway 08/26 at 10,000 feet and Runway 14/32 at 7,701 feet, providing significant operational flexibility for diverse aircraft types. Its geographical coordinates (30.492469, -81.687813) situate the airport in a region with generally stable atmospheric conditions but potential for rapid weather development due to coastal proximity. The runway configuration allows for efficient operations under varying wind conditions.

Approach Considerations

Given the airport's two parallel and perpendicular runways, pilots have multiple approach options depending on prevailing wind vectors. Runway 08/26's longer length provides advantages for larger aircraft and offers more landing tolerance. The 30 ft mean sea level elevation suggests minimal altitude-related approach complexities, though standard instrument approach procedures should be carefully reviewed prior to operation.
