In the dashboard, in the mini app and in the morning plan, a line has appeared under the forecast about what to wear: layers for the feels-like temperature, adjustments for wind and rain, shoe choice and a warning about ice.
It's calculated not by the daily average, but by the window of the workout itself, and with regard to its type: during intervals the body heats up more than on an easy run, so the recommendation differs for them. In the profile there's a "I run cold / I run hot" toggle — it shifts the whole scale to you, and from then on the service sticks to your setting.
The practical point is simple: you don't need to remember the "plus ten" rule and do the adjustments in your head on the doorstep. A breakdown of the rule itself and its limits is in the article "How to dress from −20 to +40".
