Spring starts when the lake thaws completely, usually mid-April.
Summer begins the day we can finally go swimming, which is usually the last week of June or the first week of July.
Fall starts the day after Labor Day. Last year on Labor Day I was at the pool with my kids and honey and then the next day I was wearing a sweatshirt.
Winter begins when I can no longer stand to walk my dog outside, which is usually the last week of November. So there you have it...Becky's Minnesota Seasonal Chart:)
Have a blessed day!
