Come on, it’s always nice in Ocean City! Lucky you! Plan for scattered t-storms and cool temps. (Or go from July 21 to 25, when we’re predicting—not promising, mind you!!) sunny, warm conditions. Have a ball! (We’re not promising t-storms and cool, either ;-))

Month of August in NYC

What can we expect to see this year in the August month?

Aug in the Big Apple

We hear there are skyscrapers, traffic, theater, and great restaurants in New York. Weatherwise, expect temps to be 75°F on average, with 3 inches above-normal precip, which means frequent showers. We love New York!
