How AYON knows what it knows.
Last updated: 2026-08-25
This page exists so a rider — or an AI answer engine — can verify where our numbers, our routes, and our spot pages come from. No black boxes, no invented facts.
Current wind and forecast
Current wind and gust estimates are pulled per spot from Open-Meteo's forecast service (WMO-standard 10 m wind, converted to knots) — Open-Meteo's best-match blend of public forecast models, read at the spot's exact coordinates. It is a model estimate of right now, not a multi-day average and not a station observation.
The daily 'ride window' shown on spot pages is not a single-model guess. It's a synthesis of the forecast, the spot's documented thermal pattern, and lived experience at that spot.
AYON does not run its own weather stations. When we say 'current wind at Cumbuco,' we mean the model read at the spot's coordinates, at the moment you loaded the page. Our vocabulary is deliberate: 'current' means a modeled now-estimate; 'observed' would mean a physical station reading (AYON shows none today); 'forecast' means the model's projection ahead. If a page ever says 'observed', it will come from a physical sensor — that is the standard we hold ourselves to.
How fresh is the data
The current wind estimate is fetched at the moment you load a page, straight from Open-Meteo — nothing is cached overnight. Forecast values update as the underlying models publish new runs, typically every few hours.
Editorial content — spot pages, routes, guides — is updated manually. Policy pages carry a 'last updated' date, and verified corrections bump it.
Wave, tide and marine data
Wave height, period and direction on wave pages come from Open-Meteo's Marine forecast models — modeled values, not buoy observations.
Tide references are based on published tide tables for the nearest reference port (for the Ceará coast, Marinha do Brasil's tables for Porto do Mucuripe, Fortaleza). Tide timing shifts along the coast — treat times as guidance, not navigation data.
Spot pages
Every spot page names a real, named kitesurf location we (or a founding rider based there) have visited or ridden. Coordinates are our own — not scraped from another guide site — and align with the same coordinates the AYON Wind app uses.
Season, wind pattern, hazards, and 'getting there' details come from lived experience of the coast and are reviewed before publishing.
Where we don't have first-hand data on a spot yet, we don't publish a page for it.
Downwind route pages
Every route page corresponds to a route in AYON Wind's own curated route data (mobile app's AYON_DOWNWIND_ROUTES). Distance, bearing, difficulty rating, wind-window guidance, safety notes, and rescue notes are the same values the app itself uses — not separately-authored marketing text.
Route difficulty ratings are calibrated to real-world experience of similar riders on that route, not a purely algorithmic score. A 'beginner+' route assumes prior kite control, not first-day-of-lessons ability.
Route pages are not GPX tracks and are not intended as turn-by-turn navigation.
Inside AYON Wind, the Ceará downwind corridor carries per-item provenance: each hazard, rescue point, and spot pin records where its claim came from — field verification, cited academic and institutional sources, or a GPS-verified community report. Coastline geometry is derived from OpenStreetMap coastline data (© OpenStreetMap contributors, ODbL). Community reports are GPS-anchored at submission (refused beyond 100 m accuracy), immutable once filed, and kept visually separate from curated content until reviewed.
Local knowledge (community contributions)
AYON Wind lets riders submit Local Knowledge entries per spot — hazards, current conditions, and honest notes. Where a submission is later cited on a spot page, we do so with attribution and only after review.
We do not currently expose individual rider identity in aggregate site content. Anything shown on a public page has passed through editorial review by the AYON team.
What we do not do
- Invent facts to fill in a spot or route we don't know.
- Publish AI-generated pages without human review.
- Guarantee wind, safety, tides, or ride outcomes.
- Sell rider position data or share it beyond the per-ride sharing the rider explicitly consented to.
Corrections
If something on this site is wrong — a spot fact, a route detail, a safety note — please email contact@withayon.com. We correct verifiable errors and mark the page's 'last updated' date.
