Weather Briefing

LIFR

Houlton International Airport is currently reporting low IFR (LIFR) conditions with overcast skies at 400 feet and 10 SM visibility.

Wind Analysis

Winds are from the south-southwest (200°) at 5 knots. Runway 19 is favored with a 5-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is 10 SM. The ceiling is very low at 400 feet AGL (overcast), well below circling minimums at most airports.

Temperature & Moisture

Temperature is 2°C (36°F) with a dewpoint of 2°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 24 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers RASN, Mist, Light Showers Rain, Mist.

Pilot Recommendations

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. 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 Houlton International Airport

Overview

Houlton International Airport serves northern Maine near the Canadian border, positioned at 46.123100, -67.792099 with an elevation of 489 ft MSL. As a medium-sized airport, it provides critical aviation infrastructure for the Aroostook County region. The airport features two asphalt runways supporting diverse aviation operations.

Flying Conditions

Weather conditions at Houlton demonstrate significant variability, with Visual Flight Rules (VFR) conditions predominating at 58.8% of observations. Pilots should anticipate potential Marginal VFR conditions in approximately 25% of cases, with Instrument Flight Rules occurring in 11.5% of reports. Temperature ranges from -28°C to 28°C, creating potential challenges for aircraft performance and operations.

Notable Features

The airport's geographic location near the US-Canada border presents unique considerations for cross-border aviation. Both runways (01/19 and 05/23) measure approximately 5,000 feet in length, providing substantial operational flexibility. Prevailing westerly winds at an average of 7.1 knots with occasional gusts up to 22 knots characterize the local wind environment.

Approach Considerations

Wind data indicates consistent favorable wind alignments for both runways, with minimal average crosswind components (4.4-4.7 knots). September through November represent the most consistently favorable VFR months for flight operations. Pilots should prepare for potential visibility restrictions, with observations showing average visibility of 8.8 statute miles and occasional reduced visibility scenarios.
