💵
Tipping is not optional
Service staff earn the federal-minimum tipped wage in many states (Washington pays full minimum wage to all workers, but tipping culture is unchanged). 18-22% at restaurants is standard, not generous. Not tipping is a serious social offense.
🌡️
Fahrenheit, not Celsius
Seattle in June-July is 65-78°F (18-25°C) days, dropping to 50s°F (10-14°C) at night. Subtract 32 and divide by 1.8 to get Celsius.
🚇
Take the Link, not your car
Seattle has notorious traffic (I-5, I-90, the bridges). The Link 1 Line connects Sea-Tac, downtown, Capitol Hill, the U District, and Stadium Station — almost everything you'll want to do. Save the car for day trips.
⏱️
Bridge traffic is real
Seattle is built across multiple bodies of water — the I-90 and 520 floating bridges to Bellevue back up badly at peak hours. Allow 2x your off-peak estimate during rush hour.
🥤
Free refills are real
Soft drinks come with unlimited free refills at almost every American restaurant. Don't ask — your server will top it up. Completely normal.
☕
Coffee is the local religion
Seattle invented modern coffee culture (Starbucks #1 at Pike Place, plus countless indies — Victrola, Storyville, Espresso Vivace, Anchorhead). Order at a hole-in-the-wall, expect heavy debate over roast levels. The default is a "cortado" or "flat white."
🍺
Always carry your passport
US bars card everyone who looks under 40. Government-issued photo ID required for alcohol. Your passport is safest — some venues don't accept foreign driving licences.
💬
"How are you?" is a greeting
When a cashier or server asks "Hi, how are you?" they expect "Good, thanks!" — not an actual life update. Respond with "Good, thanks — how are you?"
💊
Healthcare is very expensive
A US hospital visit without insurance costs thousands. Buy comprehensive travel insurance before you fly. Non-negotiable.
☔
The rain stereotype is wrong (in summer)
Seattle is famously rainy October-May. But July is the driest month — averaging 0.7" rain. Locals don't carry umbrellas (it's a tourist tell). A rainshell handles any drizzle that does happen.
🍃
Cannabis is legal
Recreational cannabis is legal for adults 21+ in Washington. Dispensaries throughout Seattle. Don't smoke in public spaces, on Link platforms, or in stadiums (banned). Don't take it across state lines or back home — federal law differs.
😶
The Seattle Freeze is real but warm at sports
Locals can seem distant in everyday encounters. But at Lumen Field on a Sounders match day or a USMNT World Cup game? The city is loud, friendly, and proud. Sports erase the freeze.
