Q.Since Hawaii is fairly temperate, will succulents go dormant?
Should I still stop watering succulents from Dec-Feb? Lowest temps in my area at night is around 57F.

If your lowest temps are 57 then succulents may slow down their metabolism during the coldest months, but not necessarily go dormant. You can reduce watering to maybe once or twice a month, depending on the soil and how readily it dries out. Use a soil moisture meter to take the guess work out of when to water.
