5 Steps to Winterize a Pool in a Mild Climate

Keep the water level where it is Draining the pool is unnecessary in mild climates, as freezing is not the main threat.

Balance the chemicals Shock the pool and add algaecide to prevent stagnation and algae growth.

Use a good winter cover Choose a cover that blocks sunlight to inhibit algae and keep debris out.

Run the pump occasionally Circulate the water for a few hours every few days to maintain clarity.

Skip draining, antifreeze, and blowing out lines These steps are wasted effort unless you regularly get hard freezes. Mild winters are easier on pools, so do not overcomplicate it.
