It also helps to know what the swell is like, as a big swell is more likely to push the sea further into shore. If there’s also a westerly gale then you can guarantee some high tides.
Tidespy has several tabs of information.
The graph gives a good indication of tide height, and it’s easy to see the time of day for high and low. (Whale not included.) It's full moon today. The Tabular view gives actual times and heights of high and low tides. A 3.6 metre tide is quite high. A 3.7 metre swell in open sea and Strong SW wind make a good chance of the water coming well up the beach and filling the estuary.
