Weather Briefing
MVFRÄrna Air Base is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,500 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the north-northwest (330°) at 9 knots. Runway 03/21 is favored with a 5-knot headwind and 8-knot crosswind component.
Visibility & Ceiling
Visibility is unrestricted. The ceiling is 2500 feet AGL (overcast), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 17°C (63°F) with a dewpoint of 12°C, indicating moderate moisture conditions.
Pilot Recommendations
VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further.
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 65.2% of the time based on 13,262 observations, ESCM requires careful weather planning. IFR conditions occur in 17.7% 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 4.6 knots, making it the preferred choice in typical wind conditions.
Seasonal Considerations
The best months for VFR operations are July, June, April, when clear skies are most prevalent. Temperatures at the field range from -21°C (-6°F) to 29°C (84°F), averaging 5.2°C (41°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).
