Why the UAE pool calendar looks nothing like anywhere else's
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 practical consequence is that the same pool needs different service intensity, different chemicals and sometimes different equipment settings depending on the month. The sections below walk through the year in order, because that is how the problems actually arrive.
