This is a regional read for the whole central Pacific coast of Costa Rica — global wave model only — no public buoys nearby, so treat ranges as rougher. Mornings lean toward light winds (86% of the morning windows with data); afternoons lean toward light winds (71%). Confidence is reasonable for the first 4 days and drops to "rough estimate" after that.
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.
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 central Pacific coast of Costa Rica
The week spreads from waist-high to head-high, 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 head-high ones.
Most windows read "moderate 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 waist-high week that decides whether a board gets used.
