My Plus8 does the same.
In winter it runs at 80C. In summer at a85C+.
The higher ambient temp obviously has an effect.
The fan cuts in at about 95C+
When in traffic the temp tends to stay high and fan run more often.
It rarely happens in winter.
The car has a Morgan Al rad..
There are no apparent overheating issues so it doesn't worry me. Coolant never needs topping up.
The under bonnet temp does get quite high though. The air filter box gets to 50C and more.
