Weather Briefing
VFRMarechal Cunha Machado International Airport is currently reporting visual flight rules (VFR) conditions with broken clouds at 10,000 feet and 10 miles or greater visibility.
Wind Analysis
Winds are from the north-northeast (30°) at 6 knots. Runway 06/24 is favored with a 5-knot headwind and 3-knot crosswind component.
Visibility & Ceiling
Visibility is unrestricted. The ceiling is 10000 feet AGL (broken), well above standard VFR minimums.
Temperature & Moisture
Temperature is 26°C (79°F) with a dewpoint of 24°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. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Expected weather includes: Mist, Thunderstorm Rain. Temporary IFR conditions are forecast with Mist between 02:00Z and 12:00Z. Temporary IFR conditions are forecast with Thunderstorm Rain between 16:00Z and 22:00Z.
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. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.
This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.
