Historically, at least since I’ve lived in Central Alberta, the end of May and early June is usually wet. Here is looking back at the records I’ve measured:
| Year | May | June | July |
| 2005 | 21mm | 158mm | 53mm |
| 2006 | 57mm | 87mm | 37mm |
| 2007 | 102mm | 101mm | 21mm |
| 2008 | 90mm | 100mm | 67mm |
| 2009 | 5mm | 37mm | 51mm |
| 2010 | 49mm | 77mm | 63mm |
| 2011 | 75mm | 102mm | 49mm |
| 2012 | 75mm | 116mm | 102mm |
| 2013 | 87mm | 132mm | 31mm |
| 2014 | 73mm | 152mm | 27mm |
| 2015 | 31mm | ?mm | ?mm |

My predictions: Going to be a dry summer. Maybe 70-90mm for June?
Interesting that since 2009 our June rainfall total has continue to rise each year by 20mm or more. Is that due to more cloud seeding?
