🛷 Snowmobiling
Snowmobile weather, scored for the trail
Sledders need a base first and everything else second. BlockCast weighs snow cover at 10 out of 10 for snowmobiling, then warm spells that soften the trail, rain, wind and deep cold, and scores every block of your week so the long ride goes on the right day.
Free. No account, no ads, no tracking. iPhone, iPad and any web browser.
What BlockCast checks for snowmobiling
Every block gets a risk score from 0 to 100: green under 25, yellow under 55, red above. The worst factor drives the score and the others add to it. These are the default weights; you can change any of them in the app under Adjust.
Comfortable feels-like temperature: -25 to 4 °C (-13 to 39 °F). Wind adds risk from 20 km/h (12 mph) sustained or 38 km/h (24 mph) in gusts. Under 15 cm of snow the ground counts as bare.
How it works
- Pick snowmobiling and your spot. Use your location or search any place in the world, and save up to three.
- Read your week at a glance. Choose 2, 3, 4 or 6 hour blocks and the hours you actually play. Tap any block for the hour-by-hour detail and the reason behind its colour.
- Plan it and stop checking. Add the session to your planner and your calendar. BlockCast re-checks every forecast and tells you if a planned session turns bad.
Snowmobiling weather questions
How much snow do you need to ride?
BlockCast treats ground with less than about 15 cm (6 in) of snow as bare, and snow base carries the full 10 out of 10 weight for snowmobiling. Trails also need to be open: check your club or federation trail report before you load the trailer.
Why does a warm day score badly?
Above freezing the trail softens, ruts up and gets slushy, so heat weighs 7 out of 10 for sleds. The comfortable band is -25 to 4 °C (-13 to 39 °F) of feels-like temperature.
Does BlockCast show trail conditions?
No, it scores the weather at the point you choose. Pair it with your local trail map for grooming and closures.
Where the data comes from
Forecasts come from Open-Meteo. Rain is the wettest of three models (the local best match, ECMWF and Canada’s GEM), so a green block means they all agree. Radar is the North American composite from Environment and Climate Change Canada; official alerts come from Environment Canada and the US National Weather Service.
