The first group of charts show seasonal accumulation of rainfall, starting May 15. The first charts shows a comparison of the four main potato-producing areas. The next four charts show each area compared to previous years.
The next charts show the daily average temperatures compared to those of the past five years for Carberry, Portage, Treherne, and Winkler.
