Just wanted to correct this, which after some research I think is wrong:

Bezier Curves.
Ater some trial and error I don't think those curves are appropriate for
plotting exact numbers.

Doing some research, it looks like the key to plotting curves in PIL is
Bezier Curves. There's lots of examples out there, this one being very good:

D'oh! Indeed that works.
But oddly when changing my xTide location to "boston" (lowercase) in my
config file, I still don't get any data in public_html/forecast/tides.html.
The contents still says "Tide forecast is not available." I'm not

the forecast extension only shows tide
Also this gives me an error:

Running that line directly:
*tide -l "Boston" -f p -o /home/weewx/test.png*

Thanks for that, adding "skin = Standard" to the [StdReport] config
section fixed that error. Looking at backups of my config file, that line
has always been missing for some reason.

i forgot to mention what might be the easiest option (assuming that you do
not mind the XWindows-circa-1990s look) - just use the image that xtide
emits.
once again, write a TideGenerator, but all you do is invoke xtide with args
to emit an image. then include that image in your templates.

Right after posting I found the forecastnig extension, that has a tide
component:

It seems to fit the bill, but I'm currently getting lots of these errors
during generation:

you will probably find it easier to start from scratch. the weewx plotting
