The beach day they’ll still talk about at Christmas

What counts as a beach day

Warm but not punishing, dew point low enough that the shade still helps, rain chance low for the afternoon, wind under what turns sand into a sandblaster, and a run of those hours long enough to be worth the drive and the parking. You set the numbers for your family; the little ones and the surfers do not want the same day. UV and sunset are on the day’s card so you can plan the hat and the drive home.

How it works

Describe a good day once: a temperature range, how humid is too humid, how much rain chance you will accept, how much wind, and how many good hours in a row you need. Add the places. Perfect Day fetches five weather models every three hours, averages them hour by hour, and judges the next ten days against your rule. When a day qualifies, everyone on the account gets one plain message. When the forecast turns, one more. Otherwise, nothing — which is most weeks.
