Beach weather is coming this week

Having just returned from vacation in Canada, where the air was nice and cool, I am not thrilled about the heat coming this week. Nevertheless, for those for whom the lack of heat this summer has been a disappointment, your turn is coming.

Heat and humidity enter New England when high pressure to the south sits in such a position that it pumps the hot and humid air north. A colder-than-average pool of ocean water over the north Atlantic has likely helped suppress the formation of this pressure system, and thus limit the amount of heat we’ve had here in New England.

This week, the Bermuda high pressure system is going to pump warm and increasingly humid air northward. There’s little doubt many areas are going to reach the 90s starting Tuesday, and this type of heat will likely last through much of the work week.

The map below shows the location of the high pressure area. The high, while present, isn’t as established as is typical for late July.

There will be a few places where you can escape the heat. The coast of Maine will stay in the 70s and lower 80s most of the week, and the higher elevations will also be less than 90 degrees.

Cape Cod will also have temperatures under 90 degrees, but those areas away from the water could reach 90 degrees on Wednesday or Thursday.

In addition to the heat, we have plenty of humidity coming back. Dew Points, which measure the amount of moisture in the air, will remain in the 60s to near 70 throughout the week. The peak of the humidity will be with us from Tuesday evening through Thursday night. On Friday, the air will dry out somewhat, but not to refreshing levels.
I don’t see a general long-term break in the heat for a while. We may return to 90-degree weather again in the first day or two of August as well.


As I look into August, although the month starts above average, there are signs cooler air will return and we should see drier, more comfortable air coming back into the area from Canada.

Shower Opportunities
I have put showers in the forecast today through Tuesday. While showers are mentioned, not all of you will see them. Over the three-day period, some areas might remain entirely dry. Vegetables and other plants which need consistent water will certainly need your help with watering this week.

Quiet Tropics
July isn’t usually a very active month in the tropics, but it’s worth a look to see. The increasingly strong El Nino is likely helping to keep stronger upper-level winds blowing across the Atlantic Basin and limiting the chances of tropical development.

There will be a small tropical system along the coastline later this week, but presently the moisture from this will stay offshore and leave the area dry and warm.
