About Osvaldo Vieira International Airport

Overview

Osvaldo Vieira International Airport serves Bissau, the capital city of Guinea-Bissau, as its primary international airport. Located at an elevation of 129 feet MSL, the airport provides critical aviation infrastructure for this West African nation. The airport supports medium-sized aircraft operations with a substantial 10,499-foot runway.

Flying Conditions

Weather observations indicate predominantly marginal visual flight rules (MVFR) conditions, with 77.9% of METAR reports showing MVFR and only 20.7% pure VFR conditions. Prevailing winds from the northeast (45°) average 5.4 knots, with occasional gusts up to 20 knots. Temperature variations are moderate, ranging from 17°C to 36°C with an average of 26.7°C.

Notable Features

The airport's single runway (03/21) is an asphalt surface positioned to align well with prevailing wind patterns. Wind data suggests near-ideal runway alignment, with 100% favorable wind conditions and minimal average crosswind of just 2 knots. Visibility is consistently good, averaging 10 statute miles with extremely rare instances of reduced visibility.

Approach Considerations

September, October, and January represent the most favorable months for visual flight operations. Pilots should anticipate northeast winds and prepare for primarily MVFR conditions. The long runway and consistent wind patterns provide reliable approach and departure opportunities throughout the year.
