The seven-day average temperature across the Canadian prairies was slightly above 14 °C from June 16-22, 2025 (Fig. 1). Areas surrounding Winnipeg and Brandon received the warmest average temperatures, while areas around Calgary and Grand Prairie experienced the coolest temperatures. Over the past 30 days, the average temperature across the Canadian prairies was around 15 °C (Fig. 2), which is slightly above the long-term climate normal. Since April 1, 2025, production areas near Lethbridge AB and Winnipeg MB have been the warmest, whereas areas near Grande Prairie AB have been the coolest (Fig. 3).

The average cumulative rainfall amounts over the last seven days across the Canadian prairies was 25 mm (Fig. 4; June 16 – June 22). Locally, higher rainfall was reported in areas surrounding Calgary and Lethbridge in Alberta plus Kindersley and Rosetown in Saskatchewan; between 70 – 100 mm of rain fell in those areas (Fig. 4). Outside of the areas receiving significant rainfall events in the last 7 days, the cumulative 30-day rainfall remains less than 70 mm for most of western Canada (Fig. 5). Over the growing season (April 1-June 22, 2025), areas surrounding Lethbridge and Calgary AB have received >200 mm of cumulative rainfall, whereas much of Saskatchewan, Manitoba, and the Peace River region have received <100 mm (Fig. 6).

The seven-day average temperature across most of the Prairie growing region was above 14 °C last week (June 9 – June 15, 2025) (Fig.1). Southeastern Alberta and southwestern Saskatchewan experienced the warmest average temperatures between June 9 and June 15. Over the past 30 days, areas around Lethbridge and Swift Current have been the warmest, while areas surrounding Grand Prairie have been the coolest (Fig. 2). The far northern part of the prairie farming area, north of Grand Prairie in the Peace River region has also been quite warm in the last 30 days. Overall, the average temperature for the 2025 growing season (April 1 – June 15) is 9.5 °C, which is slightly above the long-term climate normal (Fig. 3).

Only a few areas north of Edmonton, Saskatoon, and Grand Prairie recorded more than 15 mm of rain between June 9-15, 2025 (Fig. 4). Cumulative rainfall amounts over the last 30 days are below 50 mm for much of the Prairie growing region (Fig. 5). Over the growing season, cumulative rainfall has been highest east of the Rocky Mountains in AB, and along the southern portion of the SK/MB border, which saw a significant rainfall event in May (cumulative rainfall between April 1 and June 15; Fig. 6).

Growing season temperatures have been marginally warmer than average while rainfall amounts continue to be well above average. Manitoba continues to have warm temperatures and above normal precipitation. The average 30 day temperature (May 25 – June 23, 2024) was 13.2 °C and was 0.8 °C cooler than the long term average temperature. Warmest temperatures were observed across Manitoba and the southern prairies (Figure 1). Most of the prairies have reported 30 day rainfall amounts were normal to above normal. Rainfall amounts have been greatest in eastern regions and continue to be driest across most of Alberta (Figure 2). Average cumulative rainfall (mm) over the past 30 days was 71 mm and was 138 % of climate normal values (164 % last week). Provincial 30 day values were 54 mm, 73 mm and 97 mm for Alberta, Saskatchewan, and Manitoba, respectively. What a difference a year makes; In 2023 the average temperature for May 27 to June 25 was 17.6 °C (4.4 °C warmer than 2024) and the prairie-wide average cumulative rainfall was 56 mm (104 % of climate normals).

Since April 1, the 2024 growing season average temperature has been similar to climate normal values. Warmest average temperatures were observed across a region extending from Winnipeg to Saskatoon and southwest to Lethbridge (Figure 3). Growing season rainfall has been above normal across most of the prairies (Figure 4). Near normal precipitation amounts occurred across western Alberta and western areas of the Peace River region. During May rain amounts were well above average. Over the past few weeks, rainfall amounts have been moving closer to long term normal values. Although rainfall amounts continue to be above average, precipitation amounts (relative to climate normal) are lower in late June than mid-May. For example, as of May 12, rain amounts were 221 % of long term average values. Current rain amounts have been 168 % (191 % last week) of climate normals. Cumulative rainfall has been lowest for a large region than is west of a line that extends from Regina to Grande Prairie (Figure 5).

Soil moisture values, particularly near the soil surface, can impact the development of soil-borne insect stages (e.g., overwintered or spring stages of eggs, larvae or pupae). Figure 6 presents data to show soil moisture levels (averaged for June 17-23, 2024) in the top five centimeters of soil in western Canada. Driest soil moisture conditions were observed for western regions of Saskatchewan and eastern regions of Alberta. Soil moisture values were greatest for Manitoba and the Parkland region of Saskatchewan. The data is produced from passive microwave satellite data collected by the Soil Moisture and Ocean Salinity (SMOS) satellite and converted to soil moisture using the SMOS soil moisture processor. The data are produced by the European Space Agency. Satellites are used to sense the strength of radiation emitted from the surface of the earth. There is a strong difference in the signals emitted by dry soil and wet soil. This relationship is used to calculate surface soil moisture using a model that incorporates land cover, vegetation content, surface roughness, soil texture and other factors that influence the satellite sensor. The satellite collects data every one to three days over Canada (Satellite Soil Moisture – agriculture.canada.ca).
