What it measures
The relative humidity at this section, as a percentage: how much water the air holds compared with the most it could hold at that temperature. At 100% the air is saturated.
Why it matters on the road
Humidity shapes what the sky does. Fog forms as the air nears saturation, and damp air brings frost and misted windows on cold mornings. It is also already inside Feels like.
On its own it changes nothing about the road, which is why the app never rates it. It is shown because it explains the readings that are rated.
Never rated
Humidity never carries a mark, and it never changes a section’s rating. Its LEARN sheet says so plainly: RATED — NEVER.
