Welcome to the Saskatchewan Environmental Heatmaps, developed through a partnership between Saskatchewan Pulse Growers and TerraVision360.
These maps provide weather-based insights to support producers and agronomists across Saskatchewan, with a focus on forecasted key environmental and climate conditions. Using data from a 20 km grid of virtual weather stations with hourly inputs (sourced from IBM/The Weather Company), the system generates regularly updated maps that evaluate how recent and forecasted weather conditions influence environmental risk factors.
Environmental and climate heatmaps are provided in parallel to support broader agronomic decisions and general crop management under variable weather conditions.
Due to pulse crops maturing and pre-harvest interval restrictions, the window for fungicide application is generally past. Maps will focus only on climate for the remainder of the season.

Temperature Maps: Agronomist Notes
- Seasonal to warm conditions (15-20°C average temperatures) are expected across most of Saskatchewan, with the southeast reaching 20-25°C, supporting continued crop dry down and steady harvest progress in areas not impacted by the increased rainfall.
- Daytime highs of 25-30°C are forecast across much of the province, with pockets of 30-35°C in southeastern Saskatchewan, accelerating dry down in later-seeded pulse crops.
- Mild overnight lows of 10-15°C indicate no frost risk, allowing later maturing varieties to continue maturing.
Precipitation Map: Agronomist Notes
- A broad rainfall band from the southwest to central regions before heading north is expected to bring 10-20 mm, slowing harvest progress in some areas but replenishing surface moisture following a dry finish to the season.
- Localized pockets could receive 20-35+ mm, increasing the risk of harvest delays.
- Eastern and southeastern Saskatchewan are generally forecast to receive less than 5-10 mm, supporting continued combining and helping maintain seed quality through harvest.
Growing Degree Days Map: Agronomist Notes
- Northern and east-central Saskatchewan have accumulated approximately 1,300-1,500 GDDs, with most pulse crops approaching or entering harvest maturity.
- Central Saskatchewan, has accumulated 1,500-1,600 GDDs, supporting widespread harvest readiness and rapid crop dry down.
- Southern Saskatchewan has accumulated 1,600-1,700+ GDDs, contributing to advanced maturity and earlier harvest progression.
- Continued warm temperatures this week will add to seasonal heat accumulation, helping remaining later-seeded fields move toward harvest while rainfree areas continue to make good harvest progress.
While every effort has been made to ensure the accuracy of these maps, weather-driven models are inherently uncertain, and forecasts may not be 100% precise. All outputs are based on conditions at the time of modeling and are subject to change as weather patterns evolve.
These maps are intended to serve as general decision-support tools only. They should not be relied upon as the sole basis for disease management, spray decisions, or other operational actions. Disease development and crop outcomes may be influenced by local environmental conditions, crop management practices, varietal susceptibility, and other factors not captured in the models. Users are strongly encouraged to verify risk through field scouting, on-site observations, and consultation with qualified agronomic advisors. For disease-specific decisions, refer to additional resources such as fungicide decision support tools and field-level risk assessments.
Information provided through these disease risk and environmental maps are offered to the public FOR INFORMATIONAL PURPOSES ONLY. The map creators and collaborating organizations assume no liability for decisions made or actions taken based on the use of this information.
