This was due to a warmer than average May and September. Precipitation wasabove average from May to July, and below average for August. In most cases, this did not affectcrop yields, because crop development was ahead of schedule. The harvest season went well,despite the fact that there were good precipitation levels in September and October, particularlyat Ridgetown.4
