How do tides affect swimming at Uluwatu beaches in Bali?

Tides are predictable — they're caused by gravitational pull of the Moon and Sun, not random. To know the best time for swimming, download the Tides app with a tide schedule.

At one beach in the area (technically just outside Uluwatu) it's impossible to enter the water during high tide. It's comfortable to swim when the tide level is below 1.9m per the tide chart, best entering from the left edge of the beach.

During high tide, water is comfortable for swimming almost everywhere in the Uluwatu area, though some spots can be shallow depending on the seabed. For example, the lagoon between Merusaka and Ayodya resorts allows swimming even at low tide. The best season for swimming is April to October, mainly because there's less trash on the beaches then (tide levels barely change with season).
