The advisor converts everything to Celsius internally, then maps the effective running temperature to sensible clothing bands.
Before you step outside
What should you wear for today's run?
Set temperature, wind, sun, and humidity to get a practical kit recommendation. It starts with a sticky humid 12C sunny run: singlet, shorts, thin socks, and extra water.

Wind and sun
Wind pulls heat away once you sweat. Direct sun adds warmth and usually pushes you toward lighter, more breathable gear.
Humidity
High humidity slows evaporation, so it raises the hydration prompt and usually favors less fabric over extra layers.
Use this as a starting point. Rain, trail exposure, workout intensity, stop time, and personal comfort can all change the right choice.
