Weather Briefing
IFREastmain River Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 600 feet and 15 SM visibility.
Wind Analysis
Winds are from the northwest (320°) at 10 knots. Runway 02/20 is favored with a 5-knot headwind and 9-knot crosswind component.
Visibility & Ceiling
Visibility is 15 SM. The ceiling is 600 feet AGL (overcast). Only precision approaches may be usable depending on minimums.
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
An instrument rating and IFR flight plan are required. Verify that destination and alternate approach minimums are above current and forecast conditions. 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 Eastmain River Airport
Eastmain River Airport (CZEM/ZEM) is located in Eastmain River, CA at an elevation of 24 feet MSL. The airport has 1 runway (02/20), with the longest at 3,512 feet.
Weather Profile
With VFR conditions only 54.3% of the time based on 1,258 observations, CZEM requires careful weather planning. IFR conditions occur in 13.2% of reports, and instrument proficiency is advisable for regular operations here.
Wind Patterns & Runway Selection
Prevailing winds at CZEM come from the S (180°) with an average speed of 9.9 knots and recorded gusts up to 30 knots. Calm winds are rare (1.8%), so crosswind considerations are a regular factor. Runway 02/20 offers the lowest average crosswind component at 6.6 knots, making it the preferred choice in typical wind conditions.
Seasonal Considerations
The best months for VFR operations are March, February, September, when clear skies are most prevalent. Temperatures at the field range from -34°C (-29°F) to 21°C (70°F), averaging -6.5°C (20°F). Cold weather operations require attention to aircraft preheating, de-icing, and cold-soaked fuel management. Altimeter settings typically range from 29.1 to 30.74 inHg (985-1041 hPa).
