Weather Briefing
VFRÄrna Air Base is currently reporting visual flight rules (VFR) conditions with clear skies and 10 miles or greater visibility.
Wind Analysis
Winds are from the east-northeast (70°) at 3 knots.
Visibility & Ceiling
Visibility is unrestricted. Skies are clear with unlimited ceiling.
Temperature & Moisture
Temperature is -2°C (28°F) with a dewpoint of -4°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely. Temperatures are at or below freezing. Check for icing conditions and ensure aircraft anti-ice/de-ice systems are operational if required.
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.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Ärna Air Base
Ärna Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the SE AIP for current access procedures and restrictions.
Ärna Air Base (ESCM) is located in Uppsala, SE at an elevation of 68 feet MSL. The airport has 2 runways (03/21, 08/26), with the longest at 6,594 feet.
Weather Profile
With VFR conditions only 54.8% of the time based on 9,476 observations, ESCM requires careful weather planning. IFR conditions occur in 23.1% 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 8.1 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 4.4 knots, making it the preferred choice in typical wind conditions.
Seasonal Considerations
The best months for VFR operations are September, March, October, when clear skies are most prevalent. Temperatures at the field range from -21°C (-6°F) to 23°C (73°F), averaging 2.2°C (36°F). Cold weather operations require attention to aircraft preheating, de-icing, and cold-soaked fuel management. Altimeter settings typically range from 9.79 to 10.34 inHg (332-350 hPa).
