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
- Average temperatures of 10 to 15°C are expected across most of Saskatchewan through October 8.
- Daytime highs are forecast to reach 20 to 25°C across much of southern, central, and western Saskatchewan, promoting continued crop dry down.
- Cooler conditions are expected across eastern and northeastern regions, where highs will generally remain between 15 and 20°C.
- Overnight lows are forecast to stay mostly between 5 and 10°C, reducing the likelihood of harvest interruptions from cold temperatures and frost risk, however conditions are expected to cool down by the end of the week.
Precipitation Map: Agronomist Notes
- No significant precipitation is forecast across Saskatchewan through October 8.
- Dry weather should support harvest progress, field accessibility, and continued post harvest field operations.
- The absence of rainfall will allow crops remaining in the field to continue to be ready for harvest.
Frost Maps: Agronomist Notes
- Frost-hour maps indicate little to no frost risk across Saskatchewan from October 5 to 9.
- No widespread frost events are currently forecast, with overnight temperatures expected to remain above freezing across most regions.
- The lack of frost and warm daytime temperatures should support continued harvest progress for later-harvested pulse crops, including chickpeas, soybeans, dry beans, and faba beans.
- Harvest delays related to frost are not expected during the forecast period.
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.
