This is a regional read for the whole south west coast of Western Australia — global wave model with public buoys nearby to sanity-check it. Winds are mixed across the week, so check the day table before picking a session. 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. Notes on this week's data: 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. Most of the wave energy is local wind chop rather than swell — expect a disorganised, weak surface.
Day by day: Sep 22–28, 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 south west coast of Western Australia
The week spreads from waist-high to double-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 double-overhead 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.

Holy Hypto FutureFlex Mono Flame, Holy Hypto FutureFlex Plasma, SR-71 overlap the most of this week's 14 surf windows on catalog wave-size and power spectra; the shapes that fit best are performance shortboard, hybrid and step-up. Open any of them in Quivr to see the full range chart and compare two side by side.
Which day has the most size on the south west coast of Western Australia?
Fri Sep 25 afternoon, double-overhead (reasonable estimate). Size builds Fri and Mon and eases Wed, Thu and Sun. Winds are mixed across the week, so check the day table before picking a session.
Does this apply to my exact spot?
No single spot is named or predicted here. The read describes the south west coast of Western Australia as a whole — a stretch of coast facing roughly the same direction. 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.
How often is this page updated?
Every week, with the same seven-day regional read the Quivr app shows on its Home tab. The app refreshes several times a day and also tells you which board in your own quiver fits each day.
