The refraction may be a temperature, rather than humidity, effect. Hot land, cool water - air temp low near the surface and increasing with height. Thermally caused refraction causes mirages and that's just a bending-around-the-horizon sort of thing, as your experience is. I think refraction and vertigo-like effects on balance organs would be the first two likely candidates.
