This is a graphical representation of some of the data on our main page.
| This is an estimated weather forecast over the next few hours |  |
I have reset the curves for the 6 hours prior to the last download. For longer periods, look at the 24/48/72 hour graphs. To interpret the wind speed graph, the red line shows the instantaneous wind speed (gusts), the blue line the 2 minute average wind speed and the green line is the minimum wind speed over a 1 minute period.
The cloud base is the theoretical level at which clouds would form, based on ground level conditions converted to sea level, taking into account the altitude of the weather station. It does not mean that clouds will form at that or any other height but indicates the probable height if clouds do form. The black arrow and the figure to the right give the theoretical altitude of the cloud bottoms, while the "cloudy" zone covers the probable margin of error.
