Thanks for your support Mike!

I have done this but not to a shapefile direct, but into a postgis database.
Use for loops to loop through the temporal dimension, then the lon and lat
as sub loops.
Then you create an insert string to input each line of data into the sql
database.
In our NetCDF we have 720x360 observations

Manuel,
Shapefile is for vector formats alone. Try a raster format to convert the
netCDF data.
As for the performance, you don't need to cache anything. But it may help to
tweak the GDAL_CACHEMAX setting.

Thanks for your help,
it has to be a Shapefile because we do some further processing (symbology, map

The netCDF file contains hydrodynamics point data.
