July Temperature Outlook

A good portion of the month of June continued to be cooler in southern British Columbia, while parts of the Northwest Territories such as Yellowknife or Hay River saw temperatures in the mid to high 20s in the first week of June.

On June 9, Nova Scotia received from 30 to 90 mm of rain; five days later, another system brought an additional 55 to 95 mm of rain. Many parts of southern Alberta also received their fair share of rain between June 12 to 15, with accumulations up to 100 mm. Kananaskis reported 218 mm in 72 hours.

Several severe thunderstorms rolled through Saskatchewan, Manitoba, Ontario and Quebec in June. The June 16 storm brought ping-pong ball hail size in Scarborough, ON, taking down power lines and uprooting trees. The same system made its way east, leaving 41 000 Hydro-Quebec customers without power and dropping up to 60 mm of rain in the Montréal area in less than 3 hours, causing urban flash floods. Hail the size of golf balls was reported from Pointe-Fortune/Lachute to Deux-Montagnes. In the wake of this system, peak wind gusts of 85 km/hr left over 20 000 Ontario Hydro One customers without power on June 17 in southern Ontario.

A ridge of high pressure brought high temperatures into Saskatchewan and Manitoba on June 18 and 19, with daytime maximum temperatures reaching mid to high 30s, breaking daily temperature records. The heat spread further into Ontario from June 20 to 21st. Behind the heat, severe thunderstorms developed in eastern Prairies on June 23. Baseball size hail was reported in Binscarth and Rossburn, MB, and golf ball size hail was reported in Yorkton, SK. An EF0 tornado was spotted 30 km north of Morse, SK.

On June 29th, three tornadoes were confirmed in Saskatchewan, each given a preliminary rating of EF0, which may be updated as the investigation continues.

Here is the forecast for the “temperature anomaly” for the month of July. The temperature anomaly is the “difference from normal temperatures” for the entire month.

The forecasts are categorized as follows:

  • blue indicates the probability that temperatures will be below normal; and
  • orange to red indicates the probability that temperatures will be above normal.


This is a prediction of the anomaly of the mean daily temperature at 2 metres (i.e. at standard temperature observation height). It is not a forecast of the maximum nor of the minimum daily temperature.
