Weather Briefing

MVFR

Niagara District Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,600 feet and 15 SM visibility.

Wind Analysis

Winds are from the west-northwest (300°) at 4 knots.

Visibility & Ceiling

Visibility is 15 SM. The ceiling is 2600 feet AGL (overcast), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 8°C (46°F) with a dewpoint of 6°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

Forecast Outlook

The TAF forecast covers the next 5 hours. Conditions are expected to fluctuate between VFR and MVFR. VFR pilots should be prepared for deteriorating conditions. Expected weather includes: FCST. Temporary MVFR conditions are forecast between 20:00Z and 01:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. 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 Niagara District Airport

Overview

Niagara District Airport serves the Niagara-on-the-Lake region in Canada, situated at an elevation of 321 feet MSL. The airport provides essential aviation infrastructure with three asphalt runways ranging from 2,000 to 5,000 feet in length. Its strategic location near the Niagara Peninsula offers access to a diverse regional landscape.

Flying Conditions

Weather statistics reveal predominantly VFR conditions, with 71.5% of observations indicating clear flying weather and only 6.3% of time experiencing instrument or low instrument flight rules. Prevailing southwestern winds at an average of 10.8 knots create consistent and generally predictable flying conditions. Seasonal temperature variations range from -15°C to 29°C, with September through November representing the most stable VFR months.

Notable Features

The airport features three runways with varying orientations, providing multiple landing options dependent on wind conditions. Crosswind components remain relatively moderate, averaging between 4.8 and 7.5 knots across all runways. The longest runway (06/24) at 5,000 feet offers the most substantial landing and takeoff capabilities for aircraft operating in the region.

Approach Considerations

All three runways demonstrate 100% favorable wind alignment, suggesting flexible approach options. Pilots can expect consistent visibility averaging 13.8 statute miles, with only 3.4% of observations showing reduced visibility. The southwestern wind pattern typically favors approaches on runways aligned with the 225-degree prevailing wind direction.
