Weather Profile

With VFR conditions only 51.9% of the time based on 7,785 observations, ESCM requires careful weather planning. IFR conditions occur in 25.2% of reports, and instrument proficiency is advisable for regular operations here.

Wind Patterns & Runway Selection

Prevailing winds at ESCM come from the S (180°) with an average speed of 7.8 knots and recorded gusts up to 27 knots. Calm winds are rare (0.2%), so crosswind considerations are a regular factor. Runway 03/21 offers the lowest average crosswind component at 4.5 knots, making it the preferred choice in typical wind conditions.

Seasonal Considerations

The best months for VFR operations are September, October, March, when clear skies are most prevalent. Temperatures at the field range from -21°C (-6°F) to 23°C (73°F), averaging 1.7°C (35°F). Cold weather operations require attention to aircraft preheating, de-icing, and cold-soaked fuel management. Altimeter settings typically range from 9.84 to 10.34 inHg (333-350 hPa).
