not for me and the beach businesses....temps in the 60s with a wind at the shore isnt pleasant for the start of summer

 

this cool rainy weather sucks, we had some good warm sunny stretches but it was fools gold....now temps in 50s for two days this weekend and a cool friday barely in the low 60s heading into saturday

the other thing you have to worry about with the wind is that it makes umbrellas lethal.

I never understood the unofficial start to summer for beaches in late May. Water is still very cold and temps can be very chilly too with any east wind. 

To me the 4th of July weekend is the real start to summer.

In 2021, NYC had back to back days with high temps of only 51 on May 29th and 30th, happens.

This afternoon is gorgeous with a refreshing breeze and temperatures in the low 70s. A few photos from Katonah:

Back in the 90s/00s definitely. I distinctly remember freezing my butt off day after day sitting on the life guard stand in June. The last few years it’s been remarkably warm. Water temps were especially warm last year. People were swimming during the air show!

For as long as I’ve lived on Long Island for me true summer doesn’t start till second week of June. Until that point it can be chilly. June 15th that’s my summer start

Yeah maybe for you, but when you account for college kids going back to school by mid-August, school sports starting, etc, that would make it a 6 week summer. From mid August on is really no longer a big summer time. My shore place gets pretty dead then and Memorial Day weekend and June are busier.

This wind is atrocious.

I think true summertime conditions this summer will begin late probably in mid to late June. In the meantime we can catch a single day here and there like yesterday but there is virtually no chance of lasting warmth or probably of any heat. An active storm track and frequent cold fronts with the trough centered just to our east and northeast prevents it.

If it's 70 degrees and sunny and low humidity all summer, I will be a happy man.

[donsutherland1]

Tomorrow and Tuesday will be somewhat cooler but still pleasant days. However, it will turn noticeably cooler Tuesday night. Once it turns cooler, an extended period of below normal temperatures is likely.

A moderate to significant rainfall is likely Wednesday into Thursday. A gusty wind will likely accompany the rainfall. Showers could persist into Friday.

The ENSO Region 1+2 anomaly was 0.0°C and the Region 3.4 anomaly was +0.1°C for the week centered around May 7. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.55°C and the ENSO Region 3.4 anomaly has averaged -0.07°C. Neutral ENSO conditions will likely continue through at least mid summer.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was +7.83 yesterday.

The preliminary Arctic Oscillation (AO) was -0.290 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 50% probability that New York City will have a warmer than normal May (1991-2020 normal). May will likely finish with a mean temperature near 63.2° (near normal).

Isolated/scattered shower, drizzle as the upper low swings through north of use.

50 miles? I didn't think the Bronx was even 50 miles wide!

I really like that the newer forecasts have a sunny Memorial Day weekend for us now, temps near 70 and sunny all three days?

Memorial Day weekend looks to be mostly sunny so this makes me really happy :-)

So far, it’s looking good, especially Sunday and Monday.

cold water in May serves zero purpose, I wouldn't mind artificially heating the oceans to 70 degrees at the start of May. That would end the cut off problem too.  Instead of 50s with rain, we'd have 70s with rain.

Can you go over these indications?  Nothing looks above normal for the next two weeks +

[donsutherland1]

I was referring to the monthly and seasonal forecasts. Next two weeks is the close of spring.
