In most countries a pool has an opening day and a closing day. In the UAE it never closes, but it does change character completely four or five times a year. From October to April the water sits between roughly 18 and 26 degrees, chemical demand is modest, and a weekly visit is usually enough. From May onwards the water climbs past 30 degrees, chlorine starts disappearing almost as fast as it goes in, and evaporation can pull several millimetres of water out of the pool every day.

Layered over that heat cycle are the shamal winds, which arrive mainly in early summer and again in winter, carrying fine Gulf dust that acts as a nutrient delivery service for algae. Then there is the social calendar: Ramadan compresses working hours, Eid empties villas for a week, and the December-to-February stretch is when everyone suddenly remembers they own a heater. A good maintenance plan anticipates all of this rather than reacting to it.

The two Eids create a different problem: demand spikes just before them, as households hosting family want the pool spotless, and then supply dips during the holidays themselves as crews take leave. A pre-Eid deep clean is one of the most commonly requested one-off jobs of the year, and the good providers are booked out days ahead. Plan for it the way you would plan a pre-Eid salon appointment.

Because Ramadan moves about eleven days earlier each year, its interaction with the pool calendar keeps changing. A Ramadan that falls in winter is operationally easy; one that falls in June, as it will again within the decade, combines reduced working hours with peak chemical demand, and pools that skip visits during that overlap turn green with impressive speed. Whatever the year, in-app scheduling and WhatsApp coordination with the vendor make the shifting hours much easier to manage than phone tag.

Both sanitising approaches work here, but they fail in different ways and the UAE climate stresses each of them at a specific point. Traditional chlorine dosing — trichlor tablets in a floater or feeder, topped up with liquid chlorine in summer — is cheap and simple, and every technician in the country understands it. Its weakness is the stabiliser problem described earlier: tablets keep adding cyanuric acid, and by September an undiluted pool can be chemically locked, showing chlorine on the test strip that is doing very little in the water.

Salt chlorination generates chlorine continuously by electrolysis from mildly salty water, around a tenth the salinity of the sea. Swimmers generally find the water softer, and there are no tablets to store in a 45-degree garage. The catch is the cell: hot water and heavy summer duty shorten its life, scale builds quickly given the region's hard fill water, and replacement cells are a four-figure item in dirhams. A salt pool that is not descaled and inspected before summer often limps through August producing half the chlorine it claims to.
