CorbeauCast
CorbeauCast offers temperature forecasting based on machine learning. It provides vineyards with improved temperature forecasting. Trials have shown it is more accurate than the local Met Office forecast up to 70% of the time.
CorbeauCast also provides weekly summary charts of temperatures, %RH, Growing Degree Days (GDD) and mildew At Risk Hours (ARH).
Use GDD to check anticipated phenological stages and how a season is progressing.
Use ARH when considering interventions against mildews.
CorbeauCast is suitable for weather stations from Davis, Ecowitt and Soil Moisture Sense Limited. CorbeauCast was developed and tested at Backyard-vineyard, Llanerch Vineyard and JoJo’s Vineyard (Russell’s Water, Henley-upon-Thames).

Growing Degree Days advice
Growing Degree Days (GDD) is a useful record of how much energy a vine can potentially use to grow, flower, fruit and ripen. The GDD chart shows a cumulative total of GDD throughout the season.
It can be used to follow progress against expected phenological stages, alert to unexpectedly slow development and with a long-range weather forecast, to anticipate future stages.
Use the chart below to see how the vineyard or varietal parcels are progressing against expectations.
