Betty, there is wind in Palm Springs, and the answer is that it CAN be a real issue. :-) It depends on your sensitivity to wind. On my website, www.markgps.com, I have a wind map. It shows the areas that most effected in Palm Springs. The primary months for wind are April through June. The rest of the year, there can be days that are very windy, or just breezy, or nothing at all. When it's windy, you can have days where there are sustained winds from 30 to 50 miles an hour all day long. Lawn furniture can get moved around, umbrellas will definitely get knocked over. Having an outdoor function can be difficult, unless your house is oriented in a way that protects an area from the wind.
The closer you are to the I-10, the more the wind will effect you. That is why the windmills are located along the corridor along the I-10 into the valley. The depression in the mountain range where the highway comes in is a natural passage for air exchange. When I lived on the North end of town, I looked at the wind as "a season." The south end of town was often less windy, and if I wanted to get away from the wind I would go out to dinner with the family down in South Palm Springs. That said, South Palm Springs get's it share of wind too. However it simply isn't as common. That is one of the reasons housing prices are higher to the south of town, and closer to the mountains.
