Engine temperature rising on full throttle

Temperature guage has always been quite steady, but today on a run I found that on a slight incline in 5th at about 45 mph with foot to the floor to maintain speed the temperature guage rose rapidly. I know it was hot out, but it's never done that before (or at least I hadn't noticed) any thoughts?

Could be water pump struggling to keep up, have you checked coolant levels since.

What did you do when you saw the temp rise? What happened next?

Tony, water pump was replaced last year, so I didn't suspect that.

Ajsimmo. I pulled off and shut down then let the engine cool a bit till I was prepared to pop the cap.

I checked the levels, had a think and set off with an eagle eye on the guage. Temp rose once shortly after setting off, but then seemed ok.

I asked the same question on Facebook, and the general consensus was that I should have downshifted and let it rev. I haven't had anything similar since.
