50°F is approximately 10°C. That temperature alone cannot determine your hiking outfit because wind, rain, effort and time stopped also matter.
Build an adjustable combination
Start with layers that fit together and can be added or removed. Bring suitable outer protection for the forecast. Test movement with the pack rather than assuming a thick coat is the simplest solution.
Plan for changes
A valley forecast may not describe the route's higher ground. Carry a dry spare layer and keep it protected. Someone walking slowly or stopping frequently may need a different combination from a person climbing continuously.
Use the itinerary and units correctly
Confirm whether a forecast is in Fahrenheit or Celsius before packing. Read the Atlas layering guide, then check your actual dates and elevations. A temperature-specific packing article is a starting point, not a guarantee that one outfit suits every 10°C walk.
