Please be prepared for the weather, i.e., wear warm clothing in layers. Hats, gloves, warm waterproof shoes are recommended, as are cameras and binoculars.
Check the weather for Westhampton Beach and assume that the winds will produce wind chill. It’s better to be a more-on, than a less-on, i.e., having more layers than you need is the right thing.

CRESLI 2021/2022 SEAL SIGHTINGS AT CUPSOGUE BEACH
OBSERVATIONS |
---|
Monday November 15, 2021
SEAL MONITORING SESSION
21 Harbor seals hauled-out
|
Saturday November 20, 2021
SEAL WALK
We saw just 1 harbor seal in Moriches Bay near the haulout site, but weren't able to get a photo. We later searched for and found 2 humpback whales seen about 400-800 meters from shore on the ocean side.
|
Sunday November 28, 2021
SEAL WALK
43 Atlantic harbor seals (Phoca vitulina vitulina) and 2 Atlantic gray seals (Halichoerus grypus atlantica) on the new secondary haulout area of the sandbar, NNE of what was the main haulout site at Cupsogue Beach County Park. These seals were approximately 800 yards away, in an area used when disturbed and flushed from the primary eastern haulout site. We watched a the seals reacted en-masse to an unknown disturbance to their west (based upon the rapid head turns). Over the ensuing 30 minutes, we continued to remain low and quiet and watched as the seals swam past us, a few briefly looking our way.

Wednesday December 1, 2021
SEAL MONITORING SESSION
51 Atlantic harbor seals (Phoca vitulina vitulina) and 2 Atlantic gray seals (Halichoerus grypus atlantica) on the new secondary haulout area of the sandbar, NNE of what was the main haulout site at Cupsogue Beach County Park.

SEAL WALK FOR OREGON MIDDLE SCHOOL
44 Atlantic harbor seals (Phoca vitulina vitulina) and 2 Atlantic gray seals (Halichoerus grypus atlantica) on the new secondary haulout area of the sandbar NNE of what was the main haulout site at Cupsogue Beach County Park. These seals were approximately 650 yards away. I regret to note that we were TOO LOUD and the seals reacted by jumping into the water. We left the area to allow the seals to return, which they did in about 10 minutes.
|
Saturday December 4, 2021
SEAL WALK
25-30 Atlantic harbor seals (Phoca vitulina vitulina) were hauled out very far away at the tertiary northeastern haulout area.
|
Sunday December 12, 2021

SEAL WALK FOR SAXTON MIDDLE SCHOOL
Once again the seals were far off on their haulout area to the NNE . Approximately 30-35 seals were observed and photographed
|
Sunday December 19, 2021
SEAL WALK
The winds were from the N gusting over 25 knots (31.25 mph), the water level was so high that the "new" haulout area was underwater.
No seals were hauled out and we were able to see 2 seals swimming.
No photos were taken. |
Monday December 20, 2021
SEAL MONITORING SESSION
There was no wind and the water was like glass (Beaufort Scale 0). Approximately 35 seals were seen, including a few harbor seals that were photographed swimming near the "old" haulout area across from the old overlook above the rocks.
The majority of the seals were hauled out on a new spot, even further north, almost 3/4 of a mile away. They were so far away that it was impossible to get an accurate cont. The exact reasons for this change in haulout areas are unknown. We hope that the changes are temporary and that the seals will ultimately return to their normal haulout areas soon.
|
Monday December 27, 2021
SEAL MONITORING SESSION
65 harbor seals hauled out, then flushed from the "new" haulout area in Moriches Bay. Later a harbor seal and a humpback whale were seen on the ocean side as well

While monitoring the fog-bound haulout area prior to the seal walk we found about 30 seals hauled out in their "old place," namely the area they used from 2004-2006. 1.5 hours later, the seals were still fog bound, but at their "new" distant haulout to the NE. We waited paitiently and in a short while the fog cleared to show us ~90 seals hauled out in the "new" area.

Once again, with strong winds out of the NW, seals were swimming or hauled out on the rocks and stayed in the lee of the wind. The newly named "theta right" was seen swimming. Looking back over images, it was determined that "theta right" is the entangled seal we've seen now for 13 years. It is still being strangled by plastic

After the walk Dr. Kopelman was told by Cupsogue Beach Superintendant Ryan Sommerville, of a seal on the ocean side lying at the high tide wrack line. This was a yearling harp seal. The seal was reported to the NYS Stranding Hotline (631) 369-9829. All harp seal photos were taken at 200' with a 600mm telephoto lens.

From our colleagues at NOAA Fisheries New England/Mid-Atlantic:
If you see seals on the beach, use the Rule of Thumb while watching seals to make sure you are giving them enough space.
1) Close one eye.
2) Make a thumbs up and hold your thumb so it's in line with your vision and the seal.
3) If you can see the seal from behind your thumb, you are too close so back up!

Don't forget to contact your local stranding network 631-369-9829, or our regional hotline 866-755-6622, if you think the seal needs help!
