Pack both fall and summer clothes for this month so you can dress in layers.
Light summer clothes including shorts may be worn during the warmer and sometimes humid afternoons early in October but jeans or long pants are preferred.
Somewhat heavier fall clothes are best for much of this month, especially for the cooler evenings and mornings.
A windbreaker or light jacket will come in handy for those colder days and nights.
We suggest a windbreaker from Columbia because it’s breathable and will work even on warmer days. It also has a packable hood!
A travel scarf is multi-use and good to layer when temperatures fluctuate.
