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
- Maximum temperatures remain around 15 to 20°C across northern regions and 20 to 25°C across southern Saskatchewan.
- Average temperatures are forecast to range from 10 to 15°C across most pulse growing regions, supporting continued dry down and harvest progress.
- Minimum temperatures generally remain above freezing through mid-week, delaying widespread frost impacts.
Precipitation Map: Agronomist Notes
- Dry conditions are expected to continue across most of Saskatchewan.
- Little to no precipitation is forecast across the majority of pulse growing regions, supporting harvest operations and field accessibility.
- Any precipitation that does occur is expected to be isolated and light.
Frost Maps: Agronomist Notes
- Early this week, frost is expected to occur across portions of western Saskatchewan, with many areas receiving 2 to 4 hours of frost and localized areas exceeding 4 hours.
- Little to no frost is forecast for Tuesday and Wednesday, allowing additional time for crops to mature and dry down.
- Frost risk returns Thursday across western Saskatchewan, with 2 to 6 hours of frost forecast in some areas.
- Frost risk moves into eastern regions on Friday, with 2 to 6 hours of frost forecast across portions of northern and eastern Saskatchewan with some areas exceeding 6 hours.
- Frost may help terminate green growth and advance maturity in later-seeded crops, but prolonged frost could affect seed quality where crops have not yet reached physiological maturity.
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.
