Weather Briefing

VFR

Raleigh Durham International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 4,300 feet and 10 SM visibility.

Wind Analysis

Winds are from the south-southwest (210°) at 8 knots. Runway 23 is favored with a 8-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is 4300 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 31°C (88°F) with a dewpoint of 19°C, indicating relatively dry conditions. High temperatures at this elevation may result in significant density altitude effects. Pilots should calculate density altitude and adjust performance expectations accordingly.

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.

Pilot Recommendations

Conditions are favorable for visual flight. 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 Raleigh Durham International Airport

Overview

Raleigh Durham International Airport (KRDU) serves the major metropolitan area of Raleigh and Durham in North Carolina. As a large airport situated at 435 feet above mean sea level, it provides critical aviation infrastructure for commercial, cargo, and general aviation operations in the Research Triangle region.

Flying Conditions

Located at 35.877602, -78.787498, the airport experiences variable weather typical of the southeastern United States with potential seasonal wind shifts. Pilots should be prepared for potential thermal activity and convective weather patterns common to the region, particularly during summer months.

Notable Features

The airport features three runways with significant variation in length: the primary runway 05L/23R is a 10,000-foot concrete runway, complemented by a 7,500-foot asphalt runway 05R/23L, and a shorter 3,570-foot asphalt runway 14/32. The multiple runway configuration provides operational flexibility and allows for different wind conditions and aircraft type accommodations.

Approach Considerations

Runway selection will typically depend on prevailing winds, with the longer 10,000-foot concrete runway 05L/23R being preferred for larger aircraft and commercial operations. The multiple runway orientations (05/23 and 14/32) provide options for crosswind landings and diversified approach paths based on current meteorological conditions.
