BOSTON (CBS) – Today, June 8th, marks the average first date Boston reaches 90 degrees. 2021 beat that out by a few days!

This past weekend was blazing with Logan Airport checking off 91° on Saturday and 94° on Sunday. Boston officially reached a third straight day of 90+ degrees at 11:22 a.m. Monday, making this the first official heat wave of the year. This will likely be the warmest day of the entire stretch with the forecast high of 95.

A Heat Advisory is in effect through 8 p.m. Monday for the areas shaded in orange below. The excessive heat can cause heat-related issues for those at risk. Also, you should limit strenuous outdoor activity. This is a day to keep the window closed and the A/C on.

Even though the Advisory comes to an end Monday night, the heat doesn’t stop. Tuesday has another round of 90s with even higher humidity.
