How to Pack for Denver’s October Weather
The Denver weather in October offers cool fall days with lots of sunshine. You will want to prepare with some heavier clothing this time of year.
During the day, you will probably want to wear khakis, medium to long-sleeved shirts, lighter sweaters, and full dresses. Toward the end of the month, you might need blue jeans or something thicker to keep you warm outdoors.
Some days, you can still get away with shorts too. This can change on a day-to-day basis, so be sure to watch the forecast to see if there is a day you can do this during your stay.
At night you are going to need a jacket and a heavier sweater.
Dresses can work, but check out the forecast, as the winds can kick up and make feel colder than it is. Pants are your best bet, as this is when you’d want to start bundling up to stay warm and cozy.
