Forecast: Another Heat Wave Starts In Boston

Day three of the long holiday weekend will be the hottest one we have seen a while, but humidity levels will remain relatively low. You will notice more humidity in the air, but it won’t be at oppressive levels, just yet.

If you are headed to the beach, which will be a great place to be, high tide will occur just before sunset meaning a low tide after the lunch hour.  Water temperatures remain at their highest levels of the year and will continue here for another week or so before starting the slow decline.

The record high temperature for Monday is a whopping 102 set back in 1881. While we won’t come near that Monday afternoon, the 90 degree reading Logan should reach will be the start of another heat wave in Boston. This one will last three days, Monday through Wednesday, and although I expect Thursday’s highs to stay in the upper 80s, the humidity will make it feel in the lower 90s.

There is no chance of rain until sometime Thursday. I am not sure yet if the showers arrive early or lateThursday, but I am leaning to the second half of the afternoon and evening. Friday will be the most unsettled day of the next seven and the one with the best chance of rain. After four to five days of humidity, it does appear the air will dry out for the upcoming weekend, but I still don’t see any truly cooler weather in sight.

Have a great Labor Day.

Labor Day: Sunny, with a high near 90.
