Precisely. It would be rated as, as an example 93 during the winter and 91 during the summer. AKI is AKI, all things being equal.
OP has too much of a simplistic and narrow view of the issue.

LE: OP, if your concern is how the car will run during the summer then yes, it is more likely it will run bad if you tuned it in the winter.
It's a moot point asking now since we are in November. I say yes, definitely watch it next summer and see.
How has the car run during this year?
Two tunes are usually necessary if you want balls to the wall power during both summer and winter. You may run max on the threshold of knock during winter, likely you will have to back out during the summer. My original point, which you missed, was that under normal circumstances the car can cope with this.
You've run the car during one season already and are now asking about summer in November. You should have datalogged throughout.
