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
- A peak temperature of 20–25°C is forecast across much of southern and central Saskatchewan, while northern and eastern areas are generally closer to 15–20°C. This warm day should support final harvest progress.
- Overnight minimum temperatures are generally around 0–5°C, with some localized areas approaching or dropping slightly below freezing. Any immature chickpea, soybean, faba bean or late seeded acres will have limited opportunity for further maturation as colder nights become more frequent.
- Average temperatures of approximately 5–10°C across most pulse growing regions will still support some drying during the day, but crop and seed dry down will be considerably slower than during the warmer conditions earlier this fall.
Precipitation Map: Agronomist Notes
- Most of western, central and southern Saskatchewan is forecast to remain dry, providing a good window to finish harvest and other fall field operations.
- Light precipitation of approximately 1–10 mm is possible across portions of northern and eastern Saskatchewan, but widespread significant precipitation is not expected.
- For pulse crops still in the field, the generally dry forecast should help limit additional harvest delays and repeated wetting of mature seed, which is important for maintaining seed colour and quality.
Frost Maps: Agronomist Notes
- Friday is the major frost event in the forecast, with roughly 4–6+ hours of frost across much of Saskatchewan. Longer frost duration means any remaining immature pulse crops are increasingly likely to have reduced quality.
- Frost risk drops on Saturday, becoming localized to northern and eastern Saskatchewan, while Sunday is mostly frost free across most pulse growing areas.
- Frost becomes widespread on Monday, particularly across western, central and southeastern Saskatchewan, with many areas showing 4–6+ hours.
- For pulse crops that are mature in the field, frost is less of a yield concern than harvestability and seed quality. The main priority is taking advantage of the dry periods to finish harvest before additional fall moisture and repeated freeze-thaw conditions increase the potential for quality losses.
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.
