tide prediction in France
-
Hi,
Currently windy does not provide tide prediction in France and other part of the world.
Luckily someone creates an harmonic file for OpenCPN (in french, sorry…):
http://shoreline.fr/OpenCPN_V_33/3_Essentiel/E_61_Les_marees/E_61_Marees.htm#Zone_Francehttp://www.hisse-et-oh.com/matelots/9499
You can download the file here:
http://shoreline.fr/OpenCPN_V_33/3_Essentiel/E_61_Les_marees/Harmonics_V10/Harmonics_V10.zipIt adds prediction on France, but also other countries in Europe, Africa and South America.
Maybe it can help improving the coverage of tide prediction in windy ?
Kind regards,
Adrien

Hi, that could be interesting for some Windy users. The question is to know if these data are reliable. Have you tested these tide predictions in different locations at several dates, and compared them with the SHOM tidetable? -
@idefix37
I don't know if the data is reliable enough (I am not a sailor yet…), I am just passing the information ;-)
On the website, they say that “the comparaison with the SHOM are never enormous”…From what I've see, the prediction are generally less than 10 cm different from the SHOM, the worst I have seen is 40cm different from the SHOM tidetable.
The file is in version 10, so I guess the data are improving with the time.
Anyway, if this source is interesting, maybe the windy team should contact the guy for all the detail (licence, data's updates, etc.)
EDIT: if anyone wants to compare, here are the SHOM tidetable: https://maree.shom.fr/
