Persian Rug Sales Drop in Summer

For some reason, as far as researchers and observers can tell, a whole lot of people really tend to associate antique rugs and Persian rugs with colder months. Especially in places like the East Coast and more Northern areas, there is something "wintery" about rugs. Mayeb it has to do with the stereotype of a warm rug before the hearth, or fireplace. A place to curl up when the fire dims low, maybe holding a wine glass as rain or snow falls outside. There's definitely an aspect of warming to rugs, because they are insulating.
In fact, area rugs were originally designed to keep a cave, hut, or tent warm for its nomadic inhabitants when it was cold outside. That was their primary function, evolved from animal skins that used to serve the same purpose. Rugs emerged out of a very practical need to keep warm, and only later became aesthetic and artistic expressions.
Therefore, it is common knowledge amongst most dealers in areas with seasons that colder weather tends to increase sales, and summer months show a slight dip in popularity of rug stores and the like. This is probably because people are on vacation in the summer, not thinking about renovations or home decorating. And of course the subconscious thought that rugs are for warmth, and June, July, and August are all already hot enough on their own without any help from insulating floor coverings.
The realy curiosity is that this trend continues even in places that lack a very defined change in seasonal temperatures, like Southern California. Despite the lack of snow or even very cold rain, Southern California follows the trend of a slight dip in sales in the summer months.
Maybe summer is just a messy, sandy, casual time, and rugs seem like the opposite of conducive to being messy sandy and casual.
