These environmental and climate heatmaps are developed through a partnership between Ukko Agro Inc. and Saskatchewan Pulse Growers to support Saskatchewan producers and agronomists.
Weather data is collected from a 20 km grid of virtual stations using hourly weather data from IBM/The Weather Company. Maps are generated in four-day increments for average, maximum, and minimum temperature, giving you timely updates to inform management decisions. In addition, a frost risk map is produced for each day, allowing growers to monitor and respond to potential frost events.
The maps provide producers and agronomists with the data to optimize seeding planning and predict potential emergence risks, ultimately aiming to improve yields and reduce risks associated with weather variability across Saskatchewan. Access to reliable climate data empowers growers to respond to changing conditions throughout the growing season.

Temperature Maps: Agronomist Notes
- Average temperatures remain cool (≈5–10°C) across most pulse-growing regions with slow early-season crop development.
- Daytime temperatures are cool as well but may allow short but useful field work windows.
- Cool overnight lows (≈0–5°C) will slow emergence, particularly in later-seeded fields in heavier soils.
- Pulse crops may show delayed nodulation and early vigor, especially those more advanced early seeded acres.
Precipitation Map: Agronomist Notes
- Widespread precipitation is forecast, with many areas receiving 10–30 mm, and locally higher totals in central regions.
- Soil moisture will improve in dry areas, but heavier rainfall zones may see temporary delays to seeding and limited soil surface drying in northern regions.
- Increased risk of soil crusting and seedling disease in recently seeded pulse crops where rainfall is followed by surface drying.
- Strong weed flush expected following moisture, emphasizing timely early-season weed control once fields are accessible.
Frost Maps: Agronomist Notes
- Frost risk increases after Thursday, with Friday through Saturday showing the highest risk, especially across northern and central Saskatchewan.
- Saturday night (May 16) presents the greatest risk, with 4–6 hours of frost across large pulse-growing areas.
- Sunday and Monday frost risk becomes more variable, but areas of concern continue in western and northern regions.
- Emerged pulse crops may exhibit leaf injury and growth delays; damage is usually cosmetic if growing points remain healthy.
- Avoid adding stress (rolling, post emergent herbicides) immediately before or after frost events until crop recovery is evident.
While efforts have been made to ensure the accuracy of these maps, it is important to understand that weather-driven models are inherently uncertain, and forecasts may not be 100% precise. The maps presented are based on the weather conditions at the time of the forecast and are subject to change as conditions evolve.
These maps are intended to serve as a general guide for understanding potential environmental and climate-related conditions and should not be relied upon as the sole basis for operational or management decisions. Local site conditions, land management practices, and other variables may influence outcomes beyond what is captured in the model. Where possible, verify conditions with on-site measurements and observations, and consult qualified professionals for advice tailored to your location and objectives.
