Usually the proxigean tides
Usually the proxigean tides happen when there is constructive interference of the lunar and solar tide bulges (a spring tide) AND when the moon is closest to earth (perigee). These two phenomena have to coincide for this to happen. The following website ( give you the dates for Perigee and the dates for Spring tides (new and full moon). If you can find a matching date between these two, you will find a date for an upcoming proxigean tide. Hope this helps.
