Of course as I write this it is 72 degrees outside, record 75 today, but a
front that will bring most of the ponds here some ice within a few days.
The koi and gold fish have a shock coming.

yes, and how much of a problem will this be? Does anyone really know?
I suspect we all will soon enough.
Outside air was 59*F at 1100 PM Thursday, 44*F right now (521 PM
Friday). We've had over 2" rain this week. Pond water is 38*F and it
had three inches of ice on it at two weeks ago. The fish were tranquil
and at rest at the bottom. Now they are moving around seeking , who
knows what.
Forcast is for Winter to return overnight. I fear for the worst.

One of water's characteristics is a high specific heat. In other
words, it takes a lot of heat to raise the temperature of a body of
water and a lot of cold to drop it. Hence a brief warm spell followed
by a return to seasonal temperatures has little effect on the water
temperature in a 1000 gallon pond.

This characteristic moderates air temperature variations and the fish
do not even feel it.
