This is a regional read for the whole Rhode Island coast — global wave model with public buoys nearby to sanity-check it. Mornings lean toward offshore winds (100% of the morning windows with data); afternoons lean toward offshore winds (71%). Confidence reads "rough estimate" for every day shown — treat this as a trend, not a plan.
Board ranges below are each board's full min→max spectrum from the Quivr catalog — the same chart the app draws — and "fits" counts how many of this week's half-day windows a board's wave and power windows overlap. Nothing here is a guess about a particular beach.
Estimates come from a global ocean wave model sampled offshore and translated into ranges. Actual size varies from beach to beach along this stretch; sheltered spots run smaller. Reads describe the whole coast, not one break — check wind and tide at your spot before paddling out. Reads are refreshed weekly on this page and several times a day in the Quivr app, which also matches each day against the boards in your own quiver. Notes on this week's data: Most of the wave energy is local wind chop rather than swell — expect a disorganised, weak surface. The main swell comes from a direction this coast is largely shielded from. Size is a rough guess and likely smaller than open-ocean numbers suggest. The main swell arrives at an angle to this coast, so expect the smaller end of the range on most beaches.
Day by day: Sep 21–27, 2026
Morning is 6am–noon, afternoon is noon–7pm local. Words come straight from the regional read; "No data" means the wave model had no hours for that window.

What this week asks of a board on the Rhode Island coast
The week spreads from near-flat to overhead, so a single board with a wide wave window covers more sessions than a specialist. If you own two boards, split them: one for the smallest windows and one for the overhead ones.
Most windows read "mellow, not much push" for push. A board's power midpoint tells you where it will feel alive: mellower boards on the softer windows, firmer boards when the push is there. The table shows each board's own midpoint so the call is yours.
Already own one of these?
Add it to your quiver in Quivr and the Home tab does this matching for you — every day, against your own boards, for the coast you pick. If none of your boards overlap a window, it says so rather than forcing a pick.
Shopping instead? Open two of the picks above in Compare and read the low end of the wave-size range first — on a flat to ankle-high week that decides whether a board gets used.
