YO !!
Marazion or Gwithians are the 2 main low tide spots that can be awesome.
Low tide is 9 high is 3.30 down there today.
Basically Gwithians needs SW and not too high a tide - launch by the bluff pub or sunset cafe.
Marazion is best sailed WSW to W a couple of hours around low tide.
Daymer bay is a quieter option - ive never had it good but apparently a big NW (like later today) with an hour either side of high tide.
Theres probably loads more but these should start you off.
Have a great time forecast looks epic.
