Hour-by-hour & month-by-month wind
Rideable-day share by month, all three sports
Share of days with three or more daylight hours over each sport's threshold, counted from the record at 12 kt, Windsurf 13 kt and Wing 12 kt.
Blue fill scales with the share. Selected month outlined. Threshold per row: Kite 12 kt · Windsurf 13 kt · Wing 12 kt.
Where the wind sits, September
Share of daylight hours in each speed band, blue above the threshold.
Not drawn: 3% of daylight hours under 4 kt.
When in the day, September
Share of days over 12 kt at each daylight hour.
Rideable hours, not all hours. Every wind figure in this report is the mean over hours above the threshold.
September's own records
The month's own figures from ten Septembers in the record, 2017 to 2026. Not the year's average.
What the percentage hides. A month at 80% can be twenty-four steady days or three windy weeks broken by a dead front.

Per-launch tide notes
Mid to high tide. At low tide the reef is exposed; at high tide the launch beach can disappear.
Very shallow at low tide and covered in coral. Hours per tide state unknown until tide data arrives.
Tide data not yet available for this spot. The record holds wind, air and waves, not tide. Until a tide source is connected, the tables above stay empty rather than estimated. What the guide says about tide is on the next page, in words.
The reef, the lagoon & the station’s rules
Every hazard on the spot page, repeated here in full. Read this before you get wet.
Conditions change. Check local rules and conditions before you ride.
The Tombstones wave can be massive and the reef is shallow and sharp; the station says people do get hurt. At low tide the reef is exposed, and the ideal conditions are mid to high tide in a south-south-easterly. The launch beach is small, with plenty of sharp stone and shingle, and it can disappear at high tide or after heavy seas. At Gnaraloo Bay the flat water round the corner from the boat ramp is very shallow at low tide and covered in coral; the waves about 100 m out are only for riders confident with self-rescue and long swims. Wear booties.
Kitesurfing is not allowed at the 3 Mile Lagoon: an exit there is a last resort only, if the wind drops or the kite has a problem. To the left of the Gnaraloo Bay boat ramp is the reserve, where it is illegal to fish or use powered craft, and boats return to the ramp in the afternoon. The typical south wind can be a bit offshore at the bay, which the station says only works safely with a lot of west in it. No rescue service is named by any source. In an emergency call 000.
Getting there, packing & best months
Derived from the 15 to 16.5 kt mean over the season’s rideable hours in the record, September to March, not from a fitted quiver.
Best months, Kite. Record.
Sources, and their limits
Where each section of this report comes from. Record is measured. Modelled is computed by a formula because no measurement exists yet; it looks like data and is not. Written is WindChaser's editorial copy, compiled from the sources below.
The record
Hourly wind, 2017 to 2026, from ECMWF IFS HRES via Open-Meteo: a 9 km grid, read at the cell 4.5 km from the spot. It knows the wind over the cell, not the gust on the sand in front of you, and it knows the bearing, not the coastline: "side-onshore" is a rider's reading of the bearing. Each month is counted over nine to ten years.
What we could not source for Gnaraloo
Crowds by month. The Ningaloo Marine Park zoning for Gnaraloo Bay, read in the instrument itself. Any school, hire or rescue service. A water temperature. A water quality classification, and a first-hand reading of the local vibe. Tide tables and per-launch tide windows. A station check on the wind record. Surveyed launch coordinates. A licensed photograph of Tombstones. Where any of these is missing above, the section says so rather than filling itself.
Conditions change. Check local rules and conditions before you ride.
