These days, we're able to measure ocean water temperatures from satellites more precisely than ever before. And this is leading to better monitoring of what are known as "upwelling" events at the Jersey and Delaware shores.

Upwelling occurs when the wind blows warmer ocean surface water away from the coast, allowing colder bottom water to rise and take its place. Here's a look, from space, at an upwelling event back on July 2 along the central Jersey coast. The purples represent temperatures around 60^oF, while the warmer 70^oF plus water, represented by greens, yellows and reds, has been pushed well out to sea. Here's another more recent upwelling event on July 17, this one affecting much of the Delaware shore as well, though the upwelled water's not quite as chilly as the other.

So although ocean waters, on average, will continue to warm for another month or so, there will be plenty of day-to-day variation, nearly always related to upwelling.
