I don’t live in VT. My pool experience is from decades of living near MHT. We always opened Memorial Day weekend, but we never used it until mid June because no one wanted to go in 65-70° water.
I’m not getting near a pool in May without a heater.
I feel like our true seasons line up well with the astrological ones. Deep winter is gone by 3/21, consistent summer temps by 6/21, first 30s around 9/21, and the pack establishing by 12/21.
I was referencing the euro the other day, but it’s been on its own warmer for Monday. NCEP, rgem, ukie all are record cold afternoon mins (still gotta watch the early 5z), but the euro looks decently warmer.
18z 925 temps…euro versus the field.
