We can get strong currents here but they’re not tidal. Think Gulf Stream circulation driven. That’s why most of the diving in places like Cozumel & Palm Beach County FL is drift diving. We can definitely get 2 kt currents. They’re just not tidal and therefore aren’t regular in terms of periodicity. Some dives the current is virtually nonexistent while other dives you’re sailing over the reef.
Some of our shore diving site ARE tidal such as Blue Heron Bridge due to its location in a large lagoon with a sizable inlet. Most parts of that site need to be dived at or near slack tide ideally high slack tide.

The other thing we get in the south of the UK and northern France is a large tidal range; 7 metres (22ft) isn't uncommon. Diving out of Dover is easier if leaving on low water (walking down the steep ramp) and back at higher water (walking up the shallower ramp).
