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 are forecast to range from roughly 8 to 12°C across most of Saskatchewan through Oct. 4, with the warmest conditions across western and southwestern regions.
- Daytime highs generally reach the mid-teens to low 20s, supporting continued dry-down of pulse crops and good harvest progress.
- Temperatures remain favourable for combining, particularly across western and southern Saskatchewan where warmer afternoon conditions should help fields dry quickly following overnight frost events.
Precipitation Map: Agronomist Notes
- No meaningful precipitation is forecast across Saskatchewan through this period.
- Dry weather should allow harvest operations to continue uninterrupted across most pulse growing regions.
- The lack of rainfall will help preserve seed quality in crops still standing and reduce the risk of weather related bleaching or further harvest delays.
Frost Maps: Agronomist Notes
- Frost remains the primary weather concern over the next several days.
- Oct. 1 brings the most widespread frost risk, with 4 to 6+ frost hours across portions of west-central and northwestern Saskatchewan.
- On Oct. 2, frost shifts into northeastern Saskatchewan, where localized areas may again experience 4 to 6+ hours below freezing.
- Frost risk becomes more scattered on Oct. 4, with pockets of central, northeastern, and south-central Saskatchewan forecast to receive several hours below freezing.
- Frost risk is limited on Oct. 3 and largely absent by Oct. 5.
- While most pulse crops are mature and unlikely to see yield impacts, repeated frosts may accelerate crop shutdown in later-seeded fields and immature acres.
- Frosty mornings could delay harvest starting times in affected areas until plant material has dried sufficiently for combining.
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.
