Weather Briefing
MVFRMarechal Cunha Machado International Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,700 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the south-southeast (160°) at 4 knots.
Visibility & Ceiling
Visibility is unrestricted. The ceiling is 1700 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 25°C (77°F) with a dewpoint of 23°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. Conditions are expected to remain MVFR throughout the forecast period. Temporary MVFR conditions are forecast between 19:00Z and 23:00Z. Temporary MVFR conditions are forecast between 06:00Z and 11:00Z.
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.

Overview
Marechal Cunha Machado International Airport serves São Luís, Brazil, as a medium-sized international airport located at 2.585360°S, 44.234100°W. Situated at 178 feet above mean sea level, the airport provides essential air transportation infrastructure for the Maranhão state capital region. The airport features two asphalt runways capable of handling a variety of aircraft operations.
Flying Conditions
Weather conditions at SBSL are consistently favorable for aviation, with 93.8% of observations reporting VFR conditions. The airport experiences predominantly easterly winds averaging 10.9 knots, with temperatures ranging between 21°C and 34°C and maintaining an impressive average visibility of 10 statute miles. September through November represent the most stable flying months, offering optimal meteorological conditions for pilots.
Notable Features

Both runways demonstrate near-perfect wind alignment, with 100% favorable wind conditions and minimal average crosswind components of 3.5 to 4 knots. The consistent wind patterns and extensive runway lengths accommodate a wide range of aircraft types and operational requirements.
Approach Considerations
Pilots can expect predictable approach conditions given the airport's consistent wind patterns and excellent visibility. The predominant easterly wind suggests runway 06/24 and 09/27 will typically offer direct headwind approaches. With zero reported instances of low instrument meteorological conditions and no significant fog occurrences, visual approaches are standard for most operations at this airport.
