One of the reasons the Okanagan is one of the best places to grow grapes for wine is the climate.
Since August the 1st we've had 5 mm of precip. That pretty well eliminates dry farming. The hottest it ever got during that period (Penticton weather station) was 34.2 C and the coolest daytime temp was 20.7. The mean for a 24 hour day was usually around 20.
Today we'll hit 27 later in the afternoon.
