But that's comparing apples and oranges, or maybe mangos and papayas, depending on your latitude.
Please excuse a short mathematical diversion...
If you look at solar intensity over the course of an average day, it should be a trigonometric function of the solar angle. So just knowing how high the sun gets up in the sky on a given day, you ought to be able to predict how piercing it might be. Does this make sense? At least from a plant's perspective?
Put it this way: your average solar angle at midday (74°) is about the same as our annual maximum solar angle at midday (77°). And our annual minimum midday solar angle (32°) might be about half yours (60°). And we're not even that far away from the equator compared to others in the thread.

So translating these numbers into intensity through the magic of trigonometry, our most intense sun of the year is about equal to your average daily maximum, and our least intense midday sun here in the subtropics is 3 times less powerful than your annual minimum.
This on top of horizon effects where walls and stuff will cut out the sun when it is lower in the sky.
In the end sun exposure is a function of intensity and time (the term "full sun" refers to over 6 hours a day of direct outdoor sun) and the seasons affect both variables. My Aeoniums are in full sun if you were to take an annual average, but some of them are getting less than the stated figure at this time, because there are some low walls around the patio.
