There is no shelter at this latitude and no bridge to the mainland. A gust at this level stops the ferries and grounds the aircraft simultaneously, which for an island of this size means it is simply cut off until the system passes. Routine here, and still consequential.

Today would rank 6 of 76 for highest value in the modelled series. Nothing about the reading changes between rows — only the yardstick.

The season here

Shetland sits under the North Atlantic storm track all winter. The islands are engineered for wind; they still get closed by it.

Where this series comes from

MODELLED SERIES — not observed. Parameters set from published Lerwick winter gust climatology. The 75 annual values are synthesised by the seeded generator.

Every number on this page comes from a modelled series: 75 annual values synthesised by a seeded generator from published climatological parameters for Lerwick, Shetland. It shows how anomaly reasoning works. It is not a measurement and must not be cited as one.

How to read σ

σ counts standard deviations from this place's own normal. The sigma guide · return periods.
