What I meant was that the average high temperature range in most oceanic climates throughout the year, resemble the average highs here during the spring and autumn.
Looking at some of the highs over the next week in Chicago, and I'm thinking that some of your late spring looks like our winter. The rest of the days just look like spring or autumn days here.

Really? This week? I'm not very familiar with your average highs during the winter. Coolest high temps this week at Chicago/ORD will be 17-18C. Warmest 23C. Average high in May is 21-22C, but spring here is very variable. Especially early on.
We reach 27C+ 4 time this past April and 21C+ 8 times yet we were still below average for the month

I'm looking at different forecasts. The worst shows maximums of 13C, 11C, and 14C over the next week. While another shows maximums between 10C and 21C over the next week.
For a continental place like Chicago, I'd have to wait at least until August where I can comfortably dip in the water. Don't the lakes warm up by late July?

Those temperatures are averages over the entire lake. Shoreline temps in the southern end of the lake are higher, so some summers the lake is swimmable in June. Though I don't go in unless the water temp is at least 77F/25C which means that I would usually have to wait for late July into August and early September.
It also depends on the summer and even the previous winter's ice coverage.
Here is a graphic depicting Lake Michigan's water temps in 2013 compared with 2012
^^
In 2012 late July/Aug the Chicago shoreline temps were quite warm for swimming, around 27-28C, while in 2013 they were very chilly only, 22-23C
How many days did we get to, or above, 70 degrees in 2014 and 2015?

Dear Jean,
In 2014, the mercury reached at least 70 degrees on 137 days and on 144 days in 2015. Five of the seven additional days last year were the result of beginning- and end-of-season warmth, with one day in March and four in November. Chicago climatologist Frank Wachowski informed us that the long-term average dating to 1943 (inland locations) is 142 days, so both years were close to normal. The city’s extremes of 70-degree-plus days since 1943 range from 120 days in 1996 to 170 days in 1973.
One interesting stat surfacing from this research: Dating to 1871, there have been only two meteorological summers (June, July and August) where every day reached at least 70 degrees — 1959 and 2005.
