Source: routine METAR reports from the Iowa Environmental Mesonet archive (Iowa State University), 2023-2025. Flight categories use the FAA thresholds, widely used as a convention. A day counts when it has at least 12 reports. These are statistics of past conditions - not a forecast or a substitute for a pre-flight briefing.

METAR and TAF for ENSL

Weather reports for Sleipner A Platform are published under the ICAO code ENSL. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.

The decoder breaks the ENSL report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.

Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for ENSL, check the nearby airports listed below.

Reports always use UTC (the Z suffix). The Etc/GMT zone stays at GMT+00:00 year-round, so converting to local time is always the same shift.

The closest airports in the database, measured in a straight line from the reference point, are Johan Sverdrup Helipad (North Sea) (ENJS, 64 km), Heimdal Helipad (ENHM, 135 km), Ula Platform (ENLA, 150 km). When no report is available for ENSL, they usually give the best approximation of conditions in the area.
