Both runways show 100% favorable wind alignment and minimal average crosswind of 1.9 knots. The airport experiences fog in approximately 9% of observations, which pilots should consider during planning.

Approach Considerations

September through November represent the most consistent VFR flying months, offering optimal visual conditions. Runway selection can be straightforward due to the consistent wind patterns, with both 10/28 and 10G/28G having identical favorable wind characteristics. Pilots should be prepared for potential reduced visibility, particularly during the 12.4% of observations under LIFR conditions.
