  • UV 5 (moderate): SPF 30 sunscreen
  • Low tide at 9:10 am: more sand
  • Low tide at 7:53 pm: more sand
  • Cloudy (100% cloud cover)
  • Feels like 53 °F: chilly for the beach
  • Moderate offshore wind (13 mph): it blows floats and inflatables out to sea

Dangerous surf during beach hours. Stay out if the red flag is up, and never swim where there is no lifeguard.

Today, hour by hour

  • Swimming Dangerous · 12 ft

    12 ft waves every 11 s: dangerous for swimming. Stay out if the red flag is up. High rip current risk. If you're caught in a rip current, don't swim against it: swim parallel to shore and wave for help. Always follow the lifeguard's flags.

  • Water 58 °F

    Very cold: ease in and keep swims short.

  • Sun & sunscreen UV 5 · SPF 30

    Max UV 5 (moderate): SPF 30 sunscreen, reapplied every 2 hours.

  • Wind 13 mph

    Moderate offshore wind (13 mph). Skip the inflatables: offshore wind carries them out to sea.

  • Tide & sand 7:53 pm

    Low tide at 9:10 am and 7:53 pm: that's when there's the most sand. High tide at 2:28 am and 2:05 pm. Coefficient 97 (spring tides): little sand left at high tide.

We don't have data on jellyfish, sargassum or beach closures: ask the lifeguard or check with the local beach authority. How it works · The next 7 days

↓ Falling The tide is falling. 2 h 30 min to low tide at 7:53 pm.

Tide coefficient 94 for the 2:28 am high tide and 97 for the 2:05 pm high tide. Spring tides. The water rises and falls 5.7 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?

2026 extremes: the highest tide of the year is on November 28 (3.0 ft) and the lowest, on April 22 (-3.0 ft).

Mixed: two high and two low tides a day, but of quite different heights.

Heights above mean sea level. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. mean sea level

Tide coefficient and range in October

The biggest tides of the month came from October 1 to 2 (coefficient 99, 5.5 ft range). The smallest, on October 22 (coefficient 31, 2.1 ft).

Where this tide comes from

M · Global model

Grassy has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 2.6 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.

Model attribution: FES2022 Tide was produced by LEGOS, NOVELTIS and CLS, funded by CNES, and distributed by AVISO (https://doi.org/10.24400/527896/a01-2024.004), AVISO licence (https://www.aviso.altimetry.fr/fileadmin/documents/data/License_Aviso.pdf). Modified by TidePlanet: constants interpolated from the nearest model cells offshore; heights above mean sea level.

Sea and waves

The sea at Grassy

7-day waves

Sea stateSea state: rough

Rough Douglas 5 · fresh breeze, Beaufort 5
Waves 11 ft · 11.5 s from the southwest (221°)
Swell 10 ft · 10.1 s from the southwest
Current 1.2 mph toward the WSW

The waves you may find

  • Most commonMost common5.3 ft
  • Significant11 ft
  • Highest expectedHighest21 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 21 ft. Before heading out, expect waves of up to 21 ft.

Wind on the coast and offshore

On the coast 13 mph W · gusts 27
Offshore (11 mi ENE)Offshore 18 mph W · gusts 23

Cross-offshore wind. The coast faces southeast and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.

Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

Water warmer than normal for late October (+1.9 °F).

Today’s surf at a glance

The best window, 4:00 pm to 8:00 pm, has a good size and light offshore wind, though with big surf. 7:00 am to 10:00 am can also work, with a good size and light offshore wind, though with big surf.

An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance

The best window, 7:00 pm to 8:00 pm, combines slack water at low tide and light wind, though with a big swell and current. Also worth a look from 6:40 am to 8:30 am, with slack water at low tide and light wind, though with a big swell and current. Also worth a look from 1:40 pm to 2:30 pm, with slack water at high tide and the sun high, though with a big swell, moderate wind and current.

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.

Solunar periods

Today's activity: medium
  • 2:23–4:23 am Major · the moon passes overhead · high activity

  • 7:22–8:22 am Minor · moonset · medium activity
  • 11:33 pm–12:33 am 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.

Water depth

Shallow, gradual

Shallow, gradual bottom: you need to go 1.1 mi out for 33 ft of water.

From the shoreline (0.85 mi from Grassy) out to sea, heading southeast.

How far from shore

  • 16 ft deep0.9 mi
  • 33 ft deep1.1 mi
  • 66 ft deep1.7 mi
  • 164 ft deepnot within 3.1 mi

For fishing, swimming and diving

  • Shore fishing. Shallow, gradual bottom (16 ft at 0.9 mi): cast far from the beach and fish the high tide, when there is more water close in.
  • 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 near shore: you only reach 33 ft at 1.1 mi. For dives deeper than 33 ft, go by boat.

Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).

Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
