Weather Briefing

LIFR

Yaoundé Nsimalen International Airport is currently reporting low IFR (LIFR) conditions with broken clouds at 400 feet and 4 km visibility.

Wind Analysis

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

Visibility & Ceiling

Visibility is reduced to 4 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is very low at 400 feet AGL (broken), well below circling minimums at most airports.

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.

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 06:00Z and 08:00Z. There is a 30% probability of MVFR conditions between 08:00Z and 12:00Z. Temporary IFR conditions are forecast with Thunderstorm Rain between 14:00Z and 18:00Z.

Pilot Recommendations

Current conditions require an instrument rating, IFR-equipped aircraft, and an IFR clearance. Check approach minimums carefully as conditions may be below CAT I ILS minimums. 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.

Flying Conditions

Pilots can expect variable meteorological conditions with significant instrument meteorological conditions (IMC). Observations indicate 31.3% IFR and 60.9% MVFR conditions, suggesting frequent need for instrument flight procedures. Temperature ranges from 19°C to 35°C with an average of 24.3°C, and prevailing winds from the west (270°) at an average of 4.6 knots.

Notable Features

The airport's single runway (01/19) demonstrates excellent wind alignment, with 100% favorable wind conditions. Crosswind components average only 3.7 knots, providing relatively comfortable landing and takeoff environments. Visibility typically remains excellent, with an average of 10 statute miles and minimal occurrences of restricted visibility.

Approach Considerations

September through November represent the most consistent VFR months for operations. Pilots should anticipate primarily west-oriented wind patterns and prepare for potential instrument conditions.
