Hawaii (North Shore) winter (November to February) is treated here as an overhead to double-overhead+, punchy power band. Boards that only work at the edge of that band drop down the list; boards that cover most of it rise.
Every range below is the board's full min→max spectrum from the Quivr catalog — the same chart you see in the app's Compare view — not a midpoint bucket. Local breaks vary; treat the band as the typical winter day, then check your own spot.
Boards rank higher when their full wave window covers more of the North Shore winter band and their power midpoint fits those conditions. Catalog completeness and real ratings only break close ties. Max two boards per brand. 83 step-ups qualified; the top 7 are shown.

What North Shore winter actually asks of a step-up
Winter on Oahu's North Shore is the benchmark for power: north Pacific groundswell arrives overhead to well beyond, breaking on shallow reef with a lot of water moving. In spectrum terms that is a size band of overhead to double-overhead+ with punchy power. A step-up whose wave window tops out below that band will feel under-gunned on the good days; one that starts above it will sit and wait on the average ones.
If you already own one of these, add it to your quiver in Quivr with the exact size you ride — the quiver analysis will show where the gaps are for the rest of the year.
How to shortlist in Quivr
Open Discover, filter toward step-ups, and read the wave-size minimum and maximum on two or three candidates.
Compare your top two side by side — the power and skill bands will separate them faster than length or liters will.
Save the winner with the dimensions you would actually order, then log the sessions you ride it so your quiver reflects real use.
