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. In addition, a frost risk map is produced for each day, allowing growers to monitor and respond to potential frost events.
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
- Highs of 15 to 20°C are forecast across most of Saskatchewan through Monday, providing favourable combining conditions if enough drying occurs for field access and crop maturity.
- Overnight lows generally remain above freezing, limiting frost concerns for later seeded pulse crops but quality and harvestability could be impacted.
- No additional heat events are forecast, reducing the risk of heat related quality losses.
Precipitation Map: Agronomist Notes
- Most western regions are forecast to receive less than 10 mm, supporting uninterrupted harvest progress for drier acres.
- Precipitation forecasted for the east-central regions of Saskatchewan and southeast Saskatchewan, where 10 to 20 mm is possible and could slow combining progress.
- Rainfall remains scattered across the province.
Frost Maps: Agronomist Notes
- Frost risk increases Sunday morning across parts of west-central, northwestern, and central Saskatchewan, with localized areas expected to receive 2 to 6 hours below 0°C.
- Mature pulse crops are unlikely to be affected, but growers with immature soybeans, faba beans, or green patches in pea and lentil fields should monitor conditions closely.
Growing Degree Days Map: Agronomist Notes
- Southern Saskatchewan has accumulated 1,500 to 1,800+ GDD since May 1, supporting maturity and harvest progress in later-seeded pulse crops.
- Most central growing areas have reached 1,400 to 1,600 GDD, with the majority of pea and lentil acres at or near harvest readiness.
- Northern and northeastern regions remain closer to 1,200 to 1,400 GDD, leaving later-seeded soybeans and faba beans more reliant on remaining frost-free days.
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.
