So it looks like this year will be the latest date for the first 90 degree day since at least 1963. And if it doesn't get over 90 on Tuesday or Wednesday we may even break that record, since cooler weather is heading in after that.


Yes, this year's first 90 is on the late side but there have been a number of very tardy first 90s well after 1963. Just 11 years ago the first 90 of 2003 fell on 6/24 and in 1998 it occurred on 6/25. And in 1985 it didn't happen until 7/15. 1982 and 1972 also had first 90s in July. I have a feeling we won't hit 90 this week. Whenever the forecast says a high of 90 for NYC all of the towns around us get that hot, but Central Park usually ends up hitting 89!

Oh, OK. Thanks. I mis-read your notation about 6-16-82. Now that I read it again I see you meant that date was the latest first 90 degree temp since 1963, but not the latest ever since then. Thanks for the clarification.


I don't know if you're aware, but 2017 was the first 6/16 since 1970 where the high temperature failed to reach 70°.


I always get immensely livid when central park fails to reach 90° especially when we're in heat wave territory, when the low temp is >= mid 70s & when conditions are (near) perfect. i.e. little to no sea breeze, little to no clouds/rain and even then at times NYC still fails to reach 90°. i feel like sometimes mother nature and/or someone(s) at the NWS office is in ultimate control as to whether or not Central Park hits 90°.


Yeah, there's something about us weather "fanboys" who, for whatever reason, become agitated over this, especially when Newark or LaGuardia easily get into the 90s. What I've always posited is that Central Park's temperature rise is hindered because of its grassy surroundings rather than the concrete of airport runways (completely negating the "heat island" effect in the daytime, which seems to be a nighttime phenomenon). What's been interesting so far this year is that there have yet to be any days with highs of 88 or 89. In past years, instead of having six 90-degree reading, we'd have three or four days of 88/89 and two or three days in the 90s.
