It really depends how much time you have got.
I meet an A319 here that has flown for over 6 hours and the fuel temp is usually around M15degC. We have a long turn round time (3-4hrs) and a departure fuel of over 17tons. So the first thing I do on arrival is transfer all the fuel into the centre tank which fills the tanks with air at around zero deg nowadays. Then we refuel with fuel at around P3degC and depending on the conditions, manage to not deice many times.
To transfer 4 tons of fuel into the centre tank takes about 15 mins. So I suppose it could be a good idea to do this even on a one hour turnround. Just pumping it into the centre tank and out again would raise its temp quite a bit, especially if the OAT is well above zero, so the tanks are full of warm air for a while.
Transferring fuel to the centre tank is simple on an A320. Select the refuel switch to defuel (an orange lamp lights), switch the centre tank refuel switch to ON., open the crossfeed in the flight deck, and turn on the wing pumps. You will get ECAM cautions for centre tank auto feed, and wing tank low level, but just ignore them, but remember to turn off the wing pumps when before the low px lights come on.
If your dep fuel figure is below 12600 + arrival fuel, you will have to pump it back again to fill the wings for departure, but this can be done after refuelling.
