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 10–15°C are expected across most of Saskatchewan through Friday. Cooler temperatures will slow crop dry down compared with recent weeks, particularly where pulse harvest is not yet complete.
- Overnight lows are generally expected to fall near 0°C across much of the province, with a shift toward persistent freezing conditions and little remaining opportunity for immature pulse crops to be harvested under ideal conditions.
- Cooler weather means growers with remaining pulse acres will need to rely on crop maturity, seed moisture and field conditions to complete harvest.
Precipitation Map: Agronomist Notes
- Most of Saskatchewan looks to remain dry through Friday, with little to no precipitation forecast across the majority of pulse-growing regions.
- Light precipitation of approximately 1–10 mm is possible across portions of northeastern Saskatchewan, while central, western and southern regions remain largely dry.
- Limited precipitation should help maintain field accessibility and harvest opportunities for any pulse crops still remaining in the field.
- Dry weather will also reduce additional wetting of mature seed, which is important for maintaining quality where harvest has been delayed.
Frost Maps: Agronomist Notes
- Frost is the main weather concern this week, with widespread and prolonged freezing conditions forecast across Saskatchewan on Wednesday and Friday.
- Wednesday shows around 6 or more hours of frost across much of the province, while Thursday generally drops back to 2–4 hours across many pulse growing regions.
- Friday brings another widespread frost event, with much of central, eastern and southern Saskatchewan showing around 6 or more hours below freezing. Frost becomes much more localized by Saturday, primarily across eastern and northern areas.
- For pulse crops still carrying green or immature seed, repeated prolonged frost can limit maturation and increase the potential for quality concerns. Crops already physiologically mature will be much less affected.
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.
