Probably the lack of sun and warmth, who gives a rats ass if the DP is 68 and the temp is 69 with east winds and heavy cloud cover. My pool is 68 degrees July flippin 13th. Should be 80 plus
Historical wet start to July. Boston has 139 years of records. Just blown away. What's odd is the areal coverage. Most July's have varied rain due to isolated nature of convection
This rainy July is my worst nightmare. Back in May we tried to tell them this would be a rainy summer but they kept on and on about this Stein character. We buried him alive.
