Lake Check

November is the month of storms on Lake Ontario.  So if we go to the International Lake Ontario - St. Lawrence River Board website - and the weekly regulation summary, it says that the outflow is expected to be the what's in the plan.

For the week ending Wed Nov 1 2017 the reading was 74.84 m (245.54 ft) and the average this time of year is 74.56m (244.62 ft).  So it looks like about a foot above last year's levels. 

We have a strong wind warning in effect.  With a weather buoy located in Grimsby, we can look at our readings.  The current conditions say that the wave height is 0.1 metres, while other places, such as South Georgian Bay have wave heights of 1.0 metres.  I hadn't realized that there is a temperature measurement in Grimsby - we're at air temperature of 12 Celsius and water temperature of 13C.

There are colour charts of the Grimsby Buoy at

Our spring and autumn lake 'breezes' delay the onset of frost.  This would be of note for our  wine harvest.  It began in 
September, and concludes in November when later season Cabernet Franc and Cabernet Sauvignon are picked. Of course the ice wines wait for the frozen temperatures of minus 8 Celsius. 

Our pictures were taken last weekend with those 'breezes' quickly moving the brooding clouds past vineyards and fields. The large tractor in the vineyard is a mechanical picker.
