Wind speeds measured today, Saturday 22 December, at 8am on the Greenwich Lightship (in the middle of the English Channel) topped 40mph (Force8) and are increasing as the low passes over to the north. In contrast, wind speeds in Reigate remain at a 10 minute maximum average of 13mph. Wind speeds are usually higher out at sea because there is less friction at the surface (fewer hills, trees etc) to slow it down. The map shows NOAA data buoys located all over the world and used by meteorologists to forecast weather. The graph is for the Greenwich Lightship this morning: note the big wind increase since the “calm before the storm” at 20:00 GMT.
