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 EHFS

Weather reports for KNMI Weather Station (Vlissingen) are published under the ICAO code EHFS. 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 EHFS 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 EHFS, check the nearby airports listed below.

Reports always use UTC (the Z suffix). The Europe/Amsterdam zone is GMT+01:00 in winter and GMT+02:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.

The closest airports in the database, measured in a straight line from the reference point, are Midden-Zeeland Airfield (Middelburg) (EHMZ, 12 km), Ursel Air Base (EBUL, 34 km), Zuienkerke Sport Aviation Airfield (EBZU, 38 km). When no report is available for EHFS, they usually give the best approximation of conditions in the area.
