What makes a kite-wave day in Ceará: period, angle, tide, hour
A kite-wave day is not a month and it is not a wave height. It is an intersection of four things, and if any one of them is missing the session is not the one you were hoping for. Here is how each behaves on this particular coast.
1. Period, not height
Height tells you how big the water is. Period tells you whether it is a wave or just chop with ambition. On this coast that distinction does most of the work, because Ceará produces two completely different kinds of water under similar-looking numbers.
Short-period energy, roughly six to eight seconds, is locally generated trade windsea. It is what you ride from July through November, it is reliable, and it is perfectly good practice water — but it is disorganised and it closes out. Long-period energy, ten seconds and up, is North Atlantic groundswell that has travelled. It arrives with shape, it walls up, and it is what makes a session memorable. It becomes frequent from December.
If you read one number before driving to the beach, read the period.
2. The angle between wind and wave
This is the number nobody publishes and the one that decides everything. What matters is not the wind direction on its own but the angle between the wind and the beach it is hitting — and because Ceará's coastline rotates while the trade does not, that angle changes as you drive west.
Side-shore, with the wind running along the wave face, is the ideal: the kite stays powered while the board does the work. Side-offshore grooms the face beautifully and is close behind — with a serious caveat below. Side-onshore still rides but the face gets soft. Straight onshore is mush. Straight offshore is not a wave-riding condition; it is a rescue.
The trade-off that defines Ceará: the direction that grooms the wave (SE, mostly mornings) is usually too light, and the direction with real power (NE, afternoons) is the one that flattens the face. Reading that trade-off day by day is the whole skill.
3. Tide, which gates the whole thing
Ceará is mesotidal — around 2.1 m of range on average and 3.0 to 3.1 m on springs — over a gently sloping shelf. That is a lot of water moving, and it means the same spot can be a flat lagoon and a breaking reef inside one cycle.
The general rule across the wave spots is mid tide or above. Paracuru is the clearest case: at low and mid tide the outer bank encloses a flat lagoon roughly 200 m across, and at high tide the same bank produces the wave. Worth repeating a warning local sources give: the lagoon can fill in early on a low tide, so do not leave it late.
We are not going to give you a tide height threshold per spot, because no published source gives one and inventing numbers is how forecast sites lose their credibility.
4. The hour
The sea breeze fills in somewhere around 11:00 to 13:00 and holds until sunset. Before that you have a land breeze that is lovely for surfing and generally too light to kite. Kite-wave in Ceará is an afternoon sport, and the earlier the season, the harder and earlier the wind arrives.
How AYON scores it
The AYON Kite-Wave Score puts those four together into one number, per hour, per spot. Wind is treated as a gate rather than a component — below roughly nine knots there is no session to rate, however good the swell is. Above that, the score weighs wind strength, the computed angle between wind and that specific beach, wave size and period.
It also tells you which single factor is holding the score down, because that is the actionable part: a day limited by period is a day to go somewhere with a better bank, and a day limited by angle is a day to drive west.

Frequently asked questions
What wind direction is best for kite-wave in Ceará?
Side-shore is ideal, which on Ceará's west coast means an easterly trade. South-easterly grooms the wave face even better but is side-offshore there, which brings a real safety cost. North-easterly has the most power but arrives closer to onshore and softens the face. There is no single best direction for the whole state, because the coastline rotates underneath a wind that does not.
What swell period do you need to kite waves?
Anything from about ten seconds up is organised groundswell and rides like a proper wave. Six to eight seconds is locally generated windsea — rideable, reliable and good practice, but disorganised and prone to closing out. On this coast the long-period days become frequent from December.
What tide is best for kite-wave in Ceará?
Mid tide or above at most of the wave spots. Ceará has a large tidal range, around 2.1 m on average and over 3 m on springs, so the same place can be a flat lagoon at low tide and a breaking bank at high. No published source gives a specific tide height per spot, so we do not publish one.
What time of day should I kite-wave in Ceará?
The afternoon. The sea breeze typically fills in between 11:00 and 13:00 and holds until sunset, while the mornings belong to a light land breeze that is excellent for surfing and usually too light to kite.
