Shade Structures and Evaporation Reduction
A shade structure is usually chosen for comfort, but it has a real, if secondary, effect on evaporation that's worth knowing about. A higher water table near the coast affects how excavation and dewatering are handled during a gunite pour, which is accounted for in the construction plan rather than treated as a surprise once digging starts.
Less Direct Sun, Less Evaporation
Direct sun exposure and wind are the two biggest evaporation drivers; a shade sail, pergola, or cabana positioned over or near a pool reduces direct heat gain on the water surface, which modestly reduces evaporation and the associated heat and chemical loss compared with a fully exposed pool.
Not a Substitute for a Cover
The effect is real but smaller than a properly used pool cover, which blocks evaporation far more directly; shade structures are worth factoring into an energy-conscious design, but a cover is still the bigger lever for a heated pool specifically.
