Cooling over the next 11 days.
Seeding conditions are open — soil is 20.4°C at 6cm and holding above 12.5°C.
Most cool-season lawns in the northern US and Canada are bluegrass, tall fescue, or a mix of the two. We assume that, and use12.5°C as the seeding threshold.
I know what grass I have
The differences are small. Ryegrass is the quickest off the mark; bluegrass is the slowest and wants the warmest soil. Everything else sits between.

Soil temperature at 6cm in Brandon, Manitoba is currently 20.4°C, and falling about 17.2°C over the next 11 days. That depth matters because it is where grass seed sits and where roots start working, and it lags air temperature by days — which is why a warm afternoon here tells you very little on its own.
Lawns in this area are typically Kentucky bluegrass with tall fescue, the usual mix for cool-season lawns at this latitude. That blend needs the soil to hold above 12.5°C before seed germinates reliably. Seeding conditions are open — soil is 20.4°C at 6cm and holding above 12.5°C.
8 of the next 10 days are good mowing days. The other 2 are held back by wet grass or soft ground. The best weekend slot right now is Saturday 9am–3pm, on the basis that dried off since a shower 1 hour ago, ground firm.
The next recommended window in Brandon opens at 7pm on Tuesday 1 September, and holds while conditions stay put. Underfoot, the ground reads as soft in places after 46mm rain over the last week.
