Palm Springs offers you about 350 days of sunshine annually. Bring new life back in the tan you spent all summer working on. It's always swimsuit weather in the desert. Palm Springs is delightfully informal and particularly when it comes to dress. Packing becomes easy, travel can be super-light.
Most days are warm and sunny year-round.
Only during the winter months, when the temperature dips significantly after dark, is warmer clothing needed. And then jeans and a sweater usually suffice. So bring lots of shorts, colorful tops and perhaps just the odd stunning silk shirt. It's all up to you. You can even plan to have a romantic dinner in your room delivered from many fine restaurants.
