Inlets, narrows, coastal river mouths, and estuaries are prime examples. But you must remember that changes in tidal currents are not usually simultaneous with changes in tidal height. For example, in a narrow inlet or opening with a large bay behind it the tidal current can still be running out at a fast clip even though the tide has been rising for an hour or two. Or, water can continue moving into the inlet long after the tide has peaked in height and is actually falling. Tidal current lag is usually greater during spring tides and smaller during neaps.
Tides also affect fishing along river mouths.
If the river's natural current is strong enough, there may be little or no in-flowing tidal current with the rising tide. Or it might flow in slowly during spring tides and not at all during neaps. Anadromous fish returning to their natal rivers depend upon the outpouring water of the ebbing tide to bring them the scent of their destination, but they still may only enter the river as the tide floods, especially if the mouth is shallow. This is typical of salmon and sea-run trout. Generally, tidal currents are weaker along an open stretch of beach or shoreline than they are in or around inlets, and consequently tidal height often has more effect on fishing.
