program as a basis for any decisions that could result in harm to
people, other organisms, or property. Check these predictions against
officially sanctioned tables. Agencies like NOAA exist because there
is a need for certifiably correct tide predictions. Do not rely on
these predictions if you need guaranteed results. There is NO WAY we
can get certified data on a zero budget. We rely on users like you to
tell us when something is wrong. Please continue to do so.
Remember that weather conditions affect tidal ranges and current
speeds, sometimes very strongly.
