It will probably be warm, and westbrook is a suburb of portland, so there aren't too many open fieldsWhat is the weather like in westbrook maine during the summer?
last summer in maine we got a lot of rain and we have gotten a lot of rain so far this spring so we might be expecting a lot of rain again this summer! But when it is nice and sunny out its usually between 75-90 degrees!
