Weather Briefing

LIFR

London Stansted Airport is currently reporting low IFR (LIFR) conditions with broken clouds at 300 feet and 4.4 km visibility.

Wind Analysis

Winds are from the northeast (50°) at 10 knots. Runway 04/22 is favored with a 10-knot headwind and 2-knot crosswind component.

Visibility & Ceiling

Visibility is reduced to 4.4 km. IFR conditions prevail and an instrument clearance is required for operations in controlled airspace. The ceiling is very low at 300 feet AGL (broken), well below circling minimums at most airports.

Temperature & Moisture

Temperature is 5°C (41°F) with a dewpoint of 4°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 27 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: Mist, Patches Fog. Temporary LIFR conditions are forecast with Mist between 03:00Z and 08:00Z. Temporary LIFR conditions are forecast between 22:00Z and 06:00Z. There is a 30% probability of LIFR conditions with Patches Fog between 01:00Z and 06:00Z.

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.

About London Stansted Airport

Overview

London Stansted Airport serves as a major international airport located northeast of central London. Positioned at 51.884998, 0.235000 with an elevation of 348 feet MSL, the airport handles significant commercial and cargo traffic. Its substantial 10,003-foot runway (04/22) supports large commercial aircraft operations.

Flying Conditions

As an airport in southeastern England, Stansted experiences typical maritime temperate climate conditions with potential for variable visibility and wind patterns. The airport's elevation at 348 feet means pilots should anticipate potential wind shear and thermal variations, particularly during seasonal transitions. Asphalt surface (ASP) runway provides standard friction characteristics.

Notable Features

The airport's single runway (04/22) offers substantial length at 10,003 feet, accommodating wide-body and long-haul aircraft types. Its geographic location northeast of London provides strategic positioning for regional and international routes. The terrain surrounding the airport is generally flat, characteristic of the Essex countryside.

Approach Considerations

Runway 04/22's significant length allows flexible approach options for various aircraft categories. Prevailing winds in the region may influence runway selection, with pilots recommended to obtain current meteorological information before approach. Standard instrument approach procedures will apply given the airport's international classification.
