Weather Briefing

MVFR

Ben Slimane Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 1,300 feet and 5 km visibility.

Wind Analysis

Winds are from the north (360°) at 5 knots. Runway 32 is favored with a 4-knot headwind and 3-knot crosswind component.

Visibility & Ceiling

Visibility is 5 km, below VFR minimums in some airspace classifications. Check local requirements before departing VFR. The ceiling is 1300 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 18°C (64°F) with a dewpoint of 15°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

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.

About Ben Slimane Airport

Ben Slimane Airport (GMMB/GMD) is located in Ben Slimane, MA at an elevation of 627 feet MSL. The airport has 1 runway (14/32), with the longest at 10,085 feet.

Weather Profile

GMMB is weather-challenged, with VFR conditions just 44.9% of the time across 5,175 observations. IFR/LIFR conditions are present 15.8% of the time, making an instrument rating essential for reliable access.

Wind Patterns & Runway Selection

Prevailing winds at GMMB come from the S (180°) with an average speed of 7.3 knots and recorded gusts up to 30 knots. Calm winds are rare (0.2%), so crosswind considerations are a regular factor. Runway 14/32 offers the lowest average crosswind component at 4.9 knots, making it the preferred choice in typical wind conditions.

Seasonal Considerations

The best months for VFR operations are November, April, September, when clear skies are most prevalent. Temperatures at the field range from 5°C (41°F) to 38°C (100°F), averaging 15.8°C (60°F). High temperatures can significantly impact aircraft performance through increased density altitude. Altimeter settings typically range from 9.97 to 10.33 inHg (338-350 hPa).
