How warm is "warm water?"
As a rule of thumb- you can comfortably hold your finger in warm water.

100°F (38°C). Yeast wake up well at this temperature.

This time of year my house is 80°F (27°C). but I heat my water a little past that (~120°F or 50°C) to compensate for cooler ingredients- you really want the dough to be around 80F.

This will apply to all yeast recipes that call for warm water.
