In Washington during September, the weather is generally mild and pleasant, but it can still be quite variable. Daytime temperatures usually range from the mid-60s to mid-70s °F (18–24 °C), with cooler days in the mountains and warmer ones in the lowlands.
Evenings and early mornings can be crisp, often dipping into the 40s–50s °F (8–12 °C), so packing warm layers is important — especially if you’re heading into higher elevations or starting activities early in the day.
Light rain or drizzle is always a possibility in the Pacific Northwest, and conditions can shift quickly. A waterproof jacket and sturdy shoes are a must. 🌲🌦

Layered Clothing: weather can shift quickly — chilly mornings, sunny afternoons, and rainy spells are all possible in one day. Pack layers you can easily add or remove as needed.
Warm Jacket or Fleece: Evenings and early mornings can be quite cold, especially near glaciers or on the water. A cozy fleece or insulated jacket is a must.
Waterproof Jacket or Rain Poncho: Light rain or drizzle is common in Washington state, so bring a waterproof outer layer to stay dry and comfortable on hikes or boat rides.
Comfortable Walking Shoes or Hiking Boots: You’ll be on your feet a lot — from exploring nature centers to glacier walks — so sturdy, broken-in footwear is essential.
Hat and Sunglasses: Even on cooler days, the sun (especially reflecting off snow and ice) can be intense. A sunhat and sunglasses will protect your eyes and face.
Breathable Clothing: Bring lightweight, breathable shirts and tops for layering. Cotton, moisture-wicking blends, or merino wool work well.
Comfortable Pants: Leggings, joggers, or hiking pants are perfect for long drives, hikes, and casual evenings.
A Few Warm-Weather Options: Include a couple of t-shirts, tank tops, and maybe shorts — sunny days do happen, especially inland.
Swimsuit

Sunscreen: Even on cooler days, the high-latitude sun (especially near water or glaciers) can be surprisingly strong. A high SPF sunscreen is a must.
Reusable Water Bottle: Stay hydrated! We’ll have gallons of water for the group, so you can refill your bottle anytime.
Daypack or Small Backpack: Perfect for carrying essentials like water, snacks, sunscreen, layers, and your “just-in-case” girl things during our hikes and outings.

Comfortable Activewear: Pack sport clothes or stretchy, breathable outfits for yoga, meditations, or just lounging comfortably after a day of adventure.

If you get motion sickness (or even if you never have—some parts of the road are really curvy), you may need pills for it. We will have some available, but if you know you require a specific kind, please bring your own. Also, don’t forget to pack any other medications you might need during the trip!
