Cloud cover values only vary by 3% from year-to-year averages, whereas the local, day-to-day variability in cloud amounts typically rises to 30% over the globe. Land is generally covered by 10-15% less cloud than the oceans, because the seas are covered with water, allowing for more evaporation .

They forecast the cloud cover, transparency and astronomical seeing, parameters which are not forecast by civil or aviation forecasts. [1] They forecast hourly data, but are limited to forecasting at most 48 hours into the future. Each individual chart provides data for only a 9 mile radius, and so are essentially point forecasts.

The convective cloud forms more frequently inland, especially on higher ground such as Dartmoor, Exmoor and Bodmin Moor, thus reducing the amount of sunshine.
