Weather Briefing

VFR

RAF Northolt is currently reporting visual flight rules (VFR) conditions with broken clouds at 7,500 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west-southwest (240°) at 7 knots. Runway 25 is favored with a 7-knot headwind and 1-knot crosswind component.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 7500 feet AGL (broken), well above standard VFR minimums.

Temperature & Moisture

Temperature is 11°C (52°F) with a dewpoint of 8°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 18 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Showers Rain, Heavy Showers Rain. Temporary MVFR conditions are forecast with Showers Rain between 12:00Z and 20:00Z. There is a 30% probability of IFR conditions with Heavy Showers Rain between 14:00Z and 19:00Z.

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.

Flying Conditions

Weather observations indicate highly favorable VFR conditions 59.3% of the time, with marginal VFR at 27.9%. Wind patterns predominantly come from the south at 180° with an average speed of 8.2 knots, though maximum gusts can reach 29 knots. Temperature ranges from -8°C to 27°C, with an average of 9.6°C, suggesting significant seasonal variation.

Notable Features

The airport features a single asphalt runway (07/25) measuring 5,545 feet in length. Wind data shows the runway experiences favorable wind conditions 100% of the time, with an average crosswind component of only 4.8 knots. Visibility is consistently good, averaging 10 statute miles with minimal fog occurrences (2.5% of observations).

Approach Considerations

September, November, and January represent the best months for visual flight conditions. Pilots should anticipate predominantly southern wind patterns when planning approaches. The runway's favorable wind alignment and low average crosswind suggest straightforward landing and takeoff procedures for most aircraft categories.
