How deep it gets off the shore

Shore diving works here: 33 ft at 0.3 mi and 66 ft at 0.65 mi from shore.

Source: NOAA U.S. Coastal Relief Model (public domain), cells of about 300 ft. For reference only: not for navigation or anchoring.

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.

The water, as seen by satellite

4 days ago (October 24) Very clear

The satellite saw very clear water in the sea off South Palm Beach, within 3.1 mi (3 pixels of 2.5 mi; Kd490 = 0.047 m⁻¹). Kd490 measures how fast blue light fades with depth: the higher it is, the murkier the water, from plankton, suspended sand or rivers.

Very clear: under 0.06 m⁻¹ (open tropical sea: Red Sea, Caribbean). Clear: up to 0.12. Slightly murky: up to 0.25. Murky: above that (coasts with rivers, estuaries).

It's what the satellite saw that day, the last one without clouds: since then, swell, wind or rain may have changed it. The likely visibility above is today's.

Satellite: NOAA CoastWatch, Kd490 from the S-NPP VIIRS (experimental product), 2.5 mi pixels. It only shows where the seabed drops below 20 m close to shore: in shallower water the satellite sees the bottom and makes the water look murkier than it is. Sources and licenses

Coral in the area

NOAA's Coral Reef Watch satellites track water heat on coral reefs every day. In the “Southeast Florida” area, which this place is in, on October 27: No heat stress: the water isn't warmer than coral can comfortably handle.

Alert level
No heat stress
Heat build-up (12 weeks)
9.6 °C-weeks · falling
Water vs. normal
1.8 °F warmer than normal

The water has cooled down, but the heat built up over the last 12 weeks is still 9.6 °C-weeks: you'll probably still see bleached or dead coral.

Bleached coral is alive but very weak: don't touch it or lean on it, and watch your fins.

Heat build-up adds up, week by week over the last three months, how far the water goes above its normal summer maximum. According to Coral Reef Watch, significant bleaching is likely from 4 °C-weeks and severe bleaching with mortality from 8.

How we work out the diving rating

We score every moment of the day, every 10 minutes, from 0 to 10, with simple fixed rules:

  • Swell: takes points away based on its height and period (a 10 s swell weighs 50% more than a 6 s one, because it reaches deeper and moves the bottom): nothing under 1.6 ft, up to 6.5 points from 9.8 ft. Surface waves count for getting in and out; we take the worse of the two.
  • Wind: takes points away from force 4, about 12 mph (1 point), up to 6 points in a gale; half a point more when it blows offshore, because it pushes surface swimmers away from shore.
  • Current: Météo-France's model current takes points away from half a knot (1 point) up to 6 points from 2 knots.
  • Slack water: where we show the tide, up to 3 points come off when the water rises or falls fast (mid-tide, especially on spring tides) and none at slack, around each high and low tide.
  • Light: half a point more with the sun high (3 hours either side of solar noon), 1.5 less at twilight and 3 less at night. Thunderstorms take away 5 and heavy rain 1.
  • Likely visibility: good, fair or poor from the swell of the previous 48 hours, the rain of the previous 72 and the wind of the previous 24. Fair takes 1 point off the day's rating and poor, 2.
  • Day's rating: the average of the best window (the stretch of 40 minutes to 3 hours with the best conditions), adjusted for likely visibility.
  • Wetsuit, by water temperature: below 50 °F, drysuit; from 50 °F, 7 mm semi-dry; from 57 °F, 7 mm wetsuit; from 64 °F, 5 mm; from 72 °F, 3 mm; from 79 °F, shorty or rash guard.

Today: the best window scores 5.0 out of 10 and visibility is likely poor, so it takes 2 off.

It's an estimate from the swell, rain and wind of the previous days, not a measurement: real visibility also depends on the bottom, plankton and nearby rivers.

Separately, when there is data, the water clarity the satellite saw in the last few days (NOAA CoastWatch Kd490, 4 km pixels): it does not change the rating.

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.

It is a guide built from models, not a guarantee: every site has its own currents and bottom. Look at the water when you get there and ask the dive shop.

Before you get in the water

  • Never dive alone: always with a buddy and, if you don't know the site, with a dive shop.
  • Check with the local dive shop or club: they know the currents, the no-dive zones and how the water is today.
  • Dive within your certification and experience, and stay within depth and no-decompression limits.
  • Fly a dive flag (diver-down or alpha flag) on a float and watch for boat traffic.
  • Marine reserves need a permit and often have quotas: ask before you go.
  • This rating doesn't replace a professional's judgment or what you see when you arrive: if the sea doesn't look right, don't go in.
