Why would tidal flooding be dependent on the time of year?

Something to do with the phases of the sun & moon leading to higher
tides
in that period maybe? If it were due to higher rainfall or winds
driving the sea
inland you'd expect it to happen more in winter.

The spring tides are higher in March and October - but in between I
suppose it must be due to higher flows down the Thames.
