Welcome to the Old Windsor WeatherCam Blog

Hi and welcome to the Old Windsor WeatherCam Blog!

I've always been interested in the weather and as a glider pilot spend more time than I ought to looking at the sky. One trick I was taught was when flying it's no good just staring at clouds as things change very slowly. Much better to look downtrack each time round the thermal turn and so build up a time-lapse view of how the sky is changing. Surprisingly your brain is very good at noticing changes like this and with a little practice you can see how things are developing.

The Old Windsor WeatherCam employs this same time-lapse technique by taking snapshots of the same view once a minute. Replaying these images in a pseudo video really shows how the weather develops.
