SoHo’s grid runs north-south, which means the buildings on Greene and Wooster (and the parallel Mercer) cast deep east-west shadows across the streets from 10 AM until 4 PM in summer. The cast-iron facades — six stories of decorative metalwork — throw a hard shadow edge unlike the brick of the West Village. Between 11 and 2, the shaded side of each block is unambiguous.
These three pick the cool side. We avoid Spring Street (wider, less shaded) for mid-afternoon and stick to the narrow north-south runs.
