I regularly see swamp-coolers in places where the humidity is above 30% by a far margin. Sure they start losing their effectiveness in such situations, but they do still provide some cooling until the humidity reaches 70 to 80%, I don't remember exactly right now. Anyway, it can be combined with an air-conditioner to improve its effectiveness.
