Sat to tues am. I was there in mid jan 2016 as well and it was cold that year. I wore jeans most days with highs only 68-70 I think. It was that damp cold kind a weather. I go often in Jan because the rates are great! Just bring layers. I will wear a sweater in the morning and stuff in my bag as it gets warm. At night I start without and pull it out of my bag as needed. I also roll up jeans to make caprisl or roll down to cover ankles if chilly. Luckily the "end" of your trip has the better weather . I know I have been HOT when it's 75 if it's sunny, midday shorts n a T kind of weather. Have a great trip and hope to see your posts when you have time.
