Information

Raw data from the CFS and GEFS models can be selected as the basis of the forecast by using the buttons at the top

The forecasts are updated daily

Which model is it better to use?

At this range the forecast is purely about trends and probabilities

Therefore, the key thing is to try and identify consistencies over several days. For example, are the forecasts consistently suggesting warmer or colder than average weather?

If time permits, it may be best to check the forecasts from both models on a daily basis
