Winter months can present challenging conditions, with LIFR (Low Instrument Flight Rules) occurring 14% of observations and temperatures ranging from -8°C to 26°C. The prevailing southwest winds at 225° average 7.7 knots, with occasional gusts up to 28 knots.

Notable Features

The airport's terrain at 1,568 feet MSL suggests a moderately elevated location with potential terrain considerations for approach and departure.
