The prime outdoor season in Fontana runs May through October along the coast, longer inland — roughly 6 months of comfortable unheated swimming — and pools here stay open and running year-round rather than being winterized. The coast swims May through October (heaters stretch it), while the Central Valley and desert run hot enough for six-plus unassisted months. Pools stay open all year, winter is mild, and evaporation — not freeze — is the seasonal enemy, especially inland.

No — Fontana pools typically run year-round with a lighter winter service cadence instead of a close. Year-round service is the norm, at a gentler winter cadence. Hard water is the defining chemistry issue in most of the state — calcium scale on tile, spillways, and salt cells — so good techs track hardness and recommend partial drains before etching starts. Wildfire ash events mean extra filter cleans some falls.
A green-to-clean recovery in Fontana typically runs $325–$625 depending on how far gone the water is — heavy algae can take multiple visits, shock treatments, and a filter deep-clean ($75–$175). If the pool sat untreated for a season, some companies recommend a drain-and-clean instead; get a firm quote after a water test rather than over the phone.
