Where this tide comes from
Old Harbour Bay has no station of its own, so we use the tide at Port Royal (TICON-4), 16 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The sea at Old Harbour Bay
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.8 ft
- Significant1.5 ft
- Highest expectedHighest3.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.1 ft. Before heading out, expect waves of up to 3.1 ft.
Wind on the coast and offshore
Onshore wind. The coast faces south and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.

Waves stay much the same all week. The biggest waves arrive on Monday 2: 2.2 ft with a period of 5 s, from the east-southeast (slight).

The best window, 11:10 am to 12:30 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.
