# limitations and attribution

Read this before you build anything that people rely on.

## These are models, not observations

There are no buoys on this stretch of coast. Every value is derived from numerical weather and ocean models.

## Offshore models under-resolve reef points

This coast is a chain of shallow, close-in point breaks, and global models resolve that badly. In our own comparisons, **NOAA WaveWatch III has read up to \~55% higher than Open-Meteo at the same hour and location** (1.36 m vs 0.88 m).

The taghazout.io site runs a 72-hour agreement check — a Pearson correlation on the swell rhythm plus a *circular* difference on direction (you cannot naively average 350° and 10°) — and shows an **agree / mixed / diverge** confidence flag. This compact feed returns the blended read.

## Tide is modelled sea level

`tide.height_m` is relative to the low point of the current forecast window. It is not a harbour-gauge reading and not chart datum.

**Do not use it for navigation.**
{% endhint %}

## Not a safety instrument

Conditions on a reef change faster than any model. Use local judgement, and if you don't know the break, ask someone who does before paddling out.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://taghazout.gitbook.io/taghazout-docs/limitations-and-attribution.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
