Weather Briefing

MVFR

Westerly State Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 11,000 feet and 5 SM visibility.

Wind Analysis

Winds are calm, presenting no crosswind concerns for any runway.

Visibility & Ceiling

Visibility is 5 SM. The ceiling is 11000 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 22°C (72°F) with a dewpoint of 21°C. The temperature-dewpoint spread is very narrow, indicating saturated or near-saturated air. Fog formation or low cloud development is likely.

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 Westerly State Airport

Overview

Westerly State Airport serves the coastal region of Rhode Island, situated at an elevation of 81 feet MSL near the southeastern Connecticut border. The airport features two asphalt runways capable of supporting medium-sized aircraft operations, providing critical transportation infrastructure for the local and regional aviation community.

Flying Conditions

Pilots can expect predominantly VFR conditions 73.6% of the time, with marginal conditions occurring approximately 14.1% of observations. Seasonal temperatures range dramatically from -15°C to 27°C, with an average around 7.4°C, presenting potential temperature-related performance considerations for aircraft. Southwest winds at an average of 7.5 knots characterize the typical wind environment, with calm conditions present 20.6% of the time.

Notable Features

Both runways demonstrate 100% wind favorability, with Runway 14/32 experiencing a slightly higher average crosswind of 5.6 knots compared to Runway 07/25's 4.3 knots. The airport's coastal location suggests potential for rapid weather changes and marine-influenced meteorological conditions. Visibility consistently remains strong, averaging 9.2 statute miles with only 2.2% of observations showing reduced visibility.

Approach Considerations

November, September, and December represent the most favorable VFR months for operations. Pilots should anticipate potential wind variations from the prevailing southwest direction, with maximum recorded wind speeds reaching 24 knots. The dual-runway configuration provides flexibility for approach and departure strategies based on current wind conditions.
