Although there is, of course, no substitute for actually being in the vineyard to know whats going on its good to keep a handle on the seasonal statistics. We use information as shown by the graphs above to help us make better viticultural decisions.These graphs are derived from an onsite weather station and can be viewed in realtime via the internet (harvest.com). They show a number of valuable stats - temperature, rainfall, windspeed and direction, humidity, soil moisture and leaf wetness. Knowing these figures can assist with spraying timing and frequencies, irrigation scheduling, seasonal GDD, and disease pressure for example.
The information can be graphed daily,weekly or monthly and is really useful to build up a picture of how the current season is progressing. In addition you can then build up a library of historical data which can also help with current decision making.
It might be a bit too small to see but from the graphs above it appears to be cold and wet. No pruning today then.
