Big Ben Wind Stats

The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Big Ben, located 17 km away (11 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Big Ben blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Big Ben. Converseley, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from.
