The daily tidal range is greatest during the Spring tide. This is when the moon and the sun are either together in the sky or they are on opposite sides of the heavens.
it is at its lowest.
The tidal range may be small in some areas due to the geography and shape of the coastline, which can limit the flow of water. Additionally, factors such as the distance from the open ocean, the depth of the water, and local weather conditions can also impact the tidal range.
High tides are a human construct: the relatively small change in the depth of water wouldn't mean much to e.g. a fish inhabiting the upper reaches of the sea. Of course, tidal range makes a difference to creatures inhabiting the land covered by the tidal range, but that's a different question.
The large tidal range in Jersey is mainly due to its geographical location in the English Channel, which experiences strong tidal currents. The funnel shape of the channel amplifies the tidal effects, resulting in a significant difference between high and low tides. Additionally, the island's relatively shallow waters further enhance the tidal range.
A spring tide has the greatest tidal range. A neap tide has a smaller tidal range.

The Bristol Channel has the 3rd biggest tidal range in the world of 15m.
Spring tides have a greater tidal range than neap tides.
Neap tides have a lesser tidal range than spring tides.
Tidal power can create noise during installation and maintenance activities, but once operational, the turbines themselves are relatively quiet. The noise is usually within acceptable limits for marine life.
