Short answer: start with the free baseline. Environment and Climate Change Canada's WeatherCAN app gives forecasts and official alerts across Canada, and Bayer's free Spray Forecast gives an hourly spray-oriented forecast for Canadian locations. Add a station service if you need measurements on your own farm, or a paid farm tool if you want forecasts and alerts organised around your farms.
How we chose and checked these tools
Each tool below:
- Is a weather tool, not a general farm-management suite (see our separate farm apps guide for those)
- Has a public product page that we opened on November 5, 2026
- Is described only from that page: cost, platforms, Canadian coverage and what it forecasts or measures
- Is not ranked. Which one fits depends on whether you need a forecast, a measurement or both

Coverage and geography
Check where a tool actually works before you compare features. Bayer's Spray Forecast is limited to Canadian locations. FarmGate describes itself as built for Western Canada. Semios's frost page speaks of North America without naming Canada, and DTN's MyDTN page does not say whether it is sold here. WeatherCAN and AgriIntel cover Canada. A missing statement is not proof that a tool is unavailable, so ask the vendor.
Frequently Asked Questions
What is the best free weather app for Canadian farmers?
There is no single answer, but two free options cover a lot. WeatherCAN from ECCC gives forecasts and official alerts, including frost advisories, across Canada. Bayer's Spray Forecast adds an hourly wind, humidity and inversion-risk forecast aimed at spraying, for Canadian locations, on the web.
Which apps send frost alerts?
WeatherCAN sends push notifications for official severe-weather and extreme-temperature alerts. Semios sends frost alerts from its in-canopy sensors by text or email, and FarmGate lists customizable alerts. AgriIntel emails frost, heat and wind alerts from each farm's forecast every three hours. These are different kinds of alert: official, sensor-based and forecast-based.
Is there an AgriIntel app for iPhone?
Not yet. There is no iOS app. AgriIntel runs in a phone browser, and a free Android companion app on Google Play works with an existing account.
Try AgriIntel's forecast, spray strip and alerts on your own farm for 14 days. A card is required at checkout; cancel before the trial ends and you won't be charged.
