Weather Briefing

VFR

Logan International Airport is currently reporting visual flight rules (VFR) conditions with scattered clouds at 25,000 feet and 10 SM visibility.

Wind Analysis

Winds are from the north (10°) at 4 knots.

Visibility & Ceiling

Visibility is 10 SM. No ceiling exists. Cloud layers reported: few at 11,000 ft, scattered at 25,000 ft.

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 14°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 30 hours. Conditions are expected to remain VFR throughout the forecast period.

Pilot Recommendations

Conditions are favorable for visual flight. 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 Logan International Airport

Overview

Logan International Airport serves as the primary commercial airport for the Boston metropolitan area, located in eastern Massachusetts. Situated at a low elevation of 20 feet MSL, the airport is a critical transportation hub with six runways supporting substantial air traffic. Its strategic coastal location makes it a key gateway for both regional and international flights.

Flying Conditions

The airport's coastal location subjects pilots to variable maritime weather conditions, with potential rapid changes in visibility and wind patterns. Multiple runways (ranging from 2,557 to 10,083 feet) provide operational flexibility across different wind conditions and aircraft types. Proximity to the Atlantic Ocean can introduce marine layer fog and wind shear challenges, particularly during seasonal transitions.

Notable Features

Logan's runway configuration includes six paved runways with lengths accommodating everything from regional jets to wide-body aircraft. The longest runway (15R/33L) extends 10,083 feet, offering substantial landing and takeoff capabilities. The airport's low elevation and complex urban surrounding terrain require precise navigation and awareness of local geographical constraints.

Approach Considerations

Runway selection typically depends on prevailing wind directions, with parallel runway pairs 04L/22R and 04R/22L offering the longest approach surfaces. Pilots should anticipate potential wind variability due to the coastal environment and urban heat island effects. The diverse runway lengths provide multiple options for different aircraft performance characteristics and operational requirements.
