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
- Daytime highs of 20-25°C are expected across most of Saskatchewan, supporting continued crop dry down and harvest progress, where precipitation is limited.
- Overnight lows generally remain 5-10°C, limiting frost risk and allowing late-seeded pulse crops additional time to mature.
- Warm, stable conditions will help reduce seed moisture and create favourable opportunities for harvest, desiccation, and swathing operations, where forecasted rains are less likely.
- The warmest conditions are expected across western, central, and southern regions, while eastern areas remain slightly cooler but still supportive of crop maturation.
Precipitation Map: Agronomist Notes
- Much of southern and east-central Saskatchewan is forecast to receive 20-50 mm, with localized areas potentially exceeding 50 mm.
- Northern and northwestern regions are expected to remain relatively dry, supporting uninterrupted harvest activity.
- Significant rainfall may slow harvest progress, reduce field accessibility, and delay dry down of mature pulse crops across southern regions.
- Where heavier rainfall occurs, growers should monitor mature crops for quality loss, bleaching and lodging concerns if harvest is delayed.
Frost Maps: Agronomist Notes
- Little to no frost is forecast across Saskatchewan from September 14-18, with frost-hour maps indicating a very low risk of widespread frost events.
- Late-seeded pulse crops and green patches will benefit from additional frost-free time to complete seed fill and advance toward harvest readiness.
- Over the next several days, rainfall poses a much greater risk to harvest progress and crop quality than frost.
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.
