Weather Briefing

IFR

Moosonee Airport is currently reporting instrument flight rules (IFR) conditions with overcast skies at 700 feet.

Wind Analysis

Winds are from the north-northeast (30°) at 4 knots.

Visibility & Ceiling

The ceiling is 700 feet AGL (overcast). Only precision approaches may be usable depending on minimums.

Temperature & Moisture

Temperature is -2°C (28°F) with a dewpoint of -3°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.

Forecast Outlook

The TAF forecast covers the next 10 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Light Showers Snow, Light Freezing Drizzle, Mist, FCST, FCST. Temporary IFR conditions are forecast with Light Showers Snow between 08:00Z and 10:00Z. Temporary MVFR conditions are forecast with Light Showers Snow between 10:00Z and 14:00Z. There is a 30% probability of IFR conditions with Light Freezing Drizzle, Mist between 10:00Z and 14:00Z.

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 Moosonee Airport

Overview

Moosonee Airport serves the remote community of Moosonee in northern Ontario, Canada. Located at 51.291100, -80.607803 with an elevation of 30 ft MSL, the airport provides critical transportation infrastructure for this isolated region. As a medium airport, it supports essential regional air services and connects this northern community to broader transportation networks.

Flying Conditions

The airport experiences highly variable weather conditions, with significant seasonal temperature ranges from -36°C to 28°C and an average temperature of -5.2°C. Flight rules are predominantly MVFR (42.1%) and VFR (40.5%), with IFR conditions occurring 15.3% of the time. Prevailing westerly winds at an average of 8.5 knots and maximum gusts of 29 knots characterize the airport's wind environment.

Notable Features

Positioned in a northern Canadian landscape, Moosonee Airport features two runways: 06/24 with 4000 ft of asphalt surface and 14/32 with 3500 ft of compacted surface. Both runways demonstrate excellent wind alignment, with 100% favorable wind coverage and modest average crosswind components of 5.3 and 5.4 knots respectively. The low elevation and geographic location suggest potential challenges with winter operations and rapid weather changes.

Approach Considerations

Pilots should anticipate generally good visibility averaging 7.3 statute miles, with only 7.7% of observations showing reduced visibility below 3 SM. October, September, and January offer the most consistent VFR conditions. Wind characteristics strongly favor both runways, providing flexible approach options with minimal wind-related constraints.
