I'm a longtime follower and infrequent poster who grew up on the South Shore but now lives in Huntington Station. I'm a little confused by the complaints about this spring. Maybe it's because I'm used to the relentless sea breezes on the South Shore, but this spring has been well above average in terms of temperature and overall weather.
My ambient station, which is well-sited and typically runs highs somewhere between LGA and FRG, is showing an average high temperature of 57.3 from March 1 through today: 52.6 in March and 63.4 in April. That feels closer to a Central Jersey spring than a Long Island one.
Even the data that @bluewave shared shows JFK/ISP at 55.5/54.3 average spring-to-date, versus normals of 52.7 and 51.9 with precip below normal.
