Water Temperature for Stripers, Fluke, Tog and Albies: When Each Bite Turns On

If there’s one number Northeast surfcasters check before the tide chart, it’s water temperature. It doesn’t tell you where the fish are on a given night, but it tells you which fish are likely to be around at all, and whether they’re in the mood to feed.

The numbers below are the ones experienced anglers and fishing writers cite, with sources. They’re rules of thumb, not laws: fish don’t read thermometers, local conditions vary, and every season is a little different. Use them as a starting point, then let your own log refine them.

Why the trend matters more than the number

A single reading tells you less than which way it’s moving. Migrating fish respond to change: stripers push north in spring as the water warms, and fall runs kick off as it cools. The same 58°F can mean “they’re just arriving” in May and “they’re leaving” in November.

Sudden drops matter too. In summer, a few days of southerly or southwesterly wind can cause upwelling along parts of the Jersey Shore, where cold water from below replaces the warm surface water and surf temperatures can fall sharply in a day or two. The bite often shuts off until it recovers.

Striped bass

• Spring: surfcasters commonly cite about 50°F as the point where stripers start hitting lures, with bait fishermen catching them in the mid-40s (StripersOnline). Back bays and rivers warm first, so that’s usually where the season starts. The late-spring surf bite in South Jersey peaks somewhere around 55 to 68°F (The Fisherman).
• Summer: around 70°F the surf bite typically slows, and bigger fish lean toward night, dawn, cooler water and moving water.
• Fall run: in New Jersey, fishing is expected to pick up as the surf cools from the low 70s into the 60s (On The Water), and the run builds from there with the bait. For many surfcasters this is the best fishing of the year. Warming water has been shifting the timing later and making it less predictable (The Fisherman).

The 77°F line for releasing stripers

Water temperature doesn’t just decide whether bass bite. It decides whether a released bass lives. Fisheries managers have long assumed about 9% of released stripers die, but a 2024 telemetry study of 100 tagged fish found mortality of roughly 5% in spring, 11% in summer and 7% in fall, rising once the water reached about 77°F (FishTalk). Those were river fish in the Chesapeake, not Northeast surf fish, but the direction is clear. When the water is that warm, fish the cool hours, use circle hooks with bait, and get fish back in the water fast.

Tautog (blackfish)

Tog are the classic cool-water fish of the rocks and jetties, and tog anglers watch the thermometer more closely than anyone.

• Spring: fish start feeding again at around 49 to 52°F and move onto the rocks as the water warms (On The Water).
• Summer: fish stay on structure but are often less eager, and many anglers take a break.
• Fall: the bite turns on as the water drops through about 60°F (On The Water), with fish shallow early and sliding deeper as it keeps cooling into November (The Fisherman).

False albacore (albies)

Albies want warm, clean water, roughly 60 to 80°F, and they leave fast when a storm muddies the water or a cold snap drops the temperature (The Fisherman; East Hampton Star). They typically show up north first, around Cape Cod and the Vineyard in late summer, and work their way south through the fall.

Fluke (summer flounder)

Honestly, we couldn’t find well-sourced temperature thresholds for fluke the way there are for stripers and tog, so we won’t pretend to give exact numbers. What’s clear is that fluke are a summer surf fish: in New Jersey, surf fluke reports cluster from June into early September (On The Water), and as the water cools in fall they head offshore and the surf bite fades.

Fluke are also sensitive to clarity. Clean, moving water usually fishes better than churned-up water, which is worth noting in your log along with the temperature.

Where to check water temperature

• NOAA stations: many NOAA CO-OPS tide stations report water temperature every few minutes. The nearest one to your spot is usually the best free source.
• Buoys: NOAA’s National Data Buoy Center has offshore and nearshore buoys. Offshore readings can be several degrees off the surf, so treat them as a trend.
• Your own thermometer: the most accurate reading for your exact spot, if you remember to take it.

Remember that bays, rivers and shallow flats warm and cool faster than the open ocean. A spot behind an inlet can be several degrees off the beach out front.

Let your log find your numbers

The ranges above are averages across a lot of water and a lot of anglers. Your spots have their own. One beach might turn on for bass at 62°F, another at 55°F. The way to find out is to record the water temperature for every trip, skunks included, and compare fish per hour fished across temperature bands. After a season or two, you’ll have your own numbers, and they’ll beat any chart, including this one.
