The warmest time of the year is usually in July. Typically when it's delayed it's because of the ocean effect (California coast) or late summer high pressure (parts of the US South). But places in the far north (45-50 N) and far from the ocean, like Montana and the Dakotas, see their warmest day of the year on average in early August as opposed to mid-July. Why is the peak of heat in this area so late?

I've also wondered about this, because you'd think they would have as little seasonal lag as possible because of their enclosement from any ocean, and they do in winter with a lot of the places having their coldest month in December. I don't get why they don't have their warmest month even close to June. No moderating effect from the oceans and no May/June fog. Stumps me atleast
In Helsinki the warmest high is on average on 4 August.
