Hard to Say......
Luggage and bags: We usually comein the summertime and it get very very hot. Around 112 degrees to 120. I always travel light when I come. A few bathing suits a sarong, some shorts,t-shirts and slippers. At night people tend to dress up alittle to go out to dinnerso a nce evening outfit is good.
Clothing/Shoes/Weather Gear: I just discovered the Aerial Tramway. I always avoided it because I always thought it would be too hot to hike or d anything strenuous in this heat. I found out that it is ALOT cooler on the mountain. So if you decide to do this, take some hiking shoes and a warm jacket.
Toiletries and Medical Supplies: Take tons of sun block because you will need it if you come in the summertime.
Camping/Beach/Outdoor Gear: When it is not summer time it can get pretty windy here so bring a coat or jacket.
Make sure to bring....
Clothing/Shoes/Weather Gear: Sunglasses, hat, bathing suit because it's HOT in Palm Springs. And, if you get a chance to get into a swimming pool, you will be glad!
Toiletries and Medical Supplies: Sunscreen (very high spf)
Miscellaneous: Hand towel (to wipe the sweat from your face), bottled water to keep hydrated, even a spray bottle containing water will provide some relief.
Don't bring your closet
Clothing/Shoes/Weather Gear: A weekend in February was a tough time to pack for. It was supposed to be 80 during the day and about 45 at night. Just summer clothes wasn't enough, I had to think of cold nights. I came to find out that I could've just packed according to the day weather and just bring a coat for night time.
During summer time, all you'll need is a bathing suit.
Camping/Beach/Outdoor Gear: Don't forget your running shoes or hiking gear, those will most likely come in handy as there are lots of hiking trails in the area.
