With our high humidity our toilet tank is sweating buckets.  Looking for a quick fix.

Check to see if your flapper valve leaks.  (Put food coloring in your tank.  It after a couple of hours without flushing the water in the bowl has begun to change color you have a leak. Replace the flapper with a red 'Bulls Eye' model . -- jim)  If it leaks, the water will stay chilled in the tank.  There are also some insulating foam products to isolate the water from the tank sides.  Home Depot carries it for a reasonable price.

I fixed my toilets with a $7 insulation kit sold at all home improvement stores. You just drain the tank, use a hairdryer to dry it, cut the foam and glue it in. In 8 hrs it's ready for use.

I tried the foam bit. It only lasted a couple of days, then the foam came loose.  I had followed the directions very carefully.

I had the same problem, my tank sweated every winter.  Recently I swapped out toilets [for] about 200$.  This toilet has a pressure tank in it inside the water tank.   I solved the problem and got a nice toilet at the same time.

The bathroom is the most humid place in the house because of taking showers or baths. Don't flush the toilet after taking a bath or shower. Try this and see if it works out OK. It is possible that the cold water going into the toilet tank while the air is moist in the bathroom is causing the tank to sweat. After a while the water in the tank should settle to the room temperature. If you don't have a bathroom exhaust fan, maybe one should be installed to remove the moist air from the room. Also, if you have a forced air heating system, and there is a register in the bathroom, open it wide and turn on the furnace fan to circulate the air out of the room. This should be done with the door partially open so that the air can escape from the room. It might not hurt to turn on the furnace also so that warm air can circulate through the bathroom and you will be fairly comfortable upon exiting the tub or shower.

If you have a hot water baseboard heating system, then you will probably need an exhaust fan in the bathroom to exhaust the moist air. The air does not circulate as rapidly over the fin tube system of a hot water heating system as it does with the forced air system.

A really quick fix is a two-piece terry toilet tank cover.   They are not available in most stores--not even Bed, Bath and Beyond.  But you can but them online at Montgomery Ward [I didn't know Montgomery Ward still existed -- jim]
