Not Legal Advice: It is illegal to sell or light fireworks in Seattle, and doing so can result in upwards of a $5,000 fine or even jail time in certain scenarios. You can, however, enjoy a campfire on the beach at Seattle's Alki Beach Park.
See Fireworks Ban or Restricted Sales/Use by County and City.
Beach Fire Rules:
Beach fire rules are outlined in detail in the Seattle Municipal Code section 18.12.270:
Light a fire ONLY in one of the installed fire containers
Use only clean, dry firewood
Please douse your fire with water, not sand
Fires are not allowed during air pollution alerts; we will post sign
Please don't remove any materials from the park, beach or dunes
Please dispose of trash and ashes in the containers provided for each. (SMC 18.12.260)
Be considerate of others--please, no loud or amplified music! (SMC 18.12.170)
Remember, no alcohol or smoking are allowed, and parks are drug-free zones.
