Seattle Busyness
Calendar

The Seattle Busyness Calendar gives you a month-by-month view of how busy the city is likely to be on any given day. Each day scores from 0 to 100, built from three data sources: Port of Seattle cruise ship schedules, major sports team home game calendars, and confirmed large citywide events. The result is a single comparable number you can use to plan sightseeing days around peak crowds.

Most Seattle travel advice tells you when cruise season or Seafair is — but not how those events stack up day by day against each other, or how they affect specific parts of the city. A Mariners day game at T-Mobile Park crowds SoDo and the nearby waterfront in the early afternoon but may clear by evening. Three cruise ships in port on a Seahawks Sunday is a different situation entirely. The index surfaces that distinction so you can pick your days with better information.

The calendar is most useful for planning first-time visits and for timing trips around high-traffic hotspots like Pike Place Market, the Seattle waterfront, the Space Needle, and Capitol Hill. It is a forward-looking planning tool based on events known in advance — not a real-time foot traffic counter.
