Diurnal: one high and one low tide a day most days.
Heights above mean lower low water (MLLW), the zero of US nautical charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLLW

The sea at Bay Saint Louis
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.4 ft
- Significant0.8 ft
- Highest expectedHighest1.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.7 ft. Before heading out, expect waves of up to 1.7 ft.
Wind on the coast and offshore
Onshore wind. The coast faces southeast and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Tuesday 3: 3.2 ft with a period of 4 s, from the east-southeast (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 73.5 °F by Tuesday 3.

Your diving day at a glance
The best window, 10:00 am to 1:00 pm, combines slack water at low 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:35–3:35 am Major · the moon passes overhead · high activity
- 2:06–4:06 pm Major · the moon passes underfoot · high activity
- 9:31–10:31 am Minor · moonset · medium activity
- 7:40–8:40 pm Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Very shallow: the water doesn't reach 16 ft within 3.1 mi. Cast far from the beach, ideally around high tide.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
