Atlantic is different.
Faro have a tidal range of more then 3 m and a large lagoon which empties and fills via two narrow channels. This is a good mix to experience strong tidal streams on its own, but adding to this relatively shallow ocean in front, swell, waves and wind and you get a nice playground.
This is the view from Heron towards Faro airport at low water. You can't really see the airport.
And later with flood the "island" disappears and the airport is visible in the background.
This tidal changes creates strong currents and form channels and ever moving sand bars. One needs some skill to navigate and anchor there. There is a good write-up about anchoring in Faro in anything sailing forum - see this thread:
I recommend this forum to all sailors - it is packed with useful information, lively discussions and some healthy arguments.
Here is example of what can happen if you are not careful. This boat was anchored in the narrow channel and they were fine for a day or more. They stayed inside the channel as they were riding on water, not on wind. The wind was E anyway, so they were fine. Last night the wind was N and when the tide changed there was no current just long enough to allow wind to push them over a sand bar.
With water going down they had no other chance but to wait for next high water.
You can see someone picking clamps in the background. The water was knee deep at the boat at low tide. With no swell and soft bottom the boat was not at risk.
Evening was better then normal:
