The city that sensors see (and hear and feel)

What the city's public real-time sensors are reporting right now — tide gauges, weather stations, stream gauges, wave buoys, bridge-clearance sensors, traffic detectors, bike counters, weather radar, aircraft and ship transponders, bus and train trackers, bike docks, the power grid, the weather satellite overhead and the seismographs underneath. Every reading below comes from a public feed your browser (or a small robot that runs every 15 minutes) is reading directly from the source.

About this page

This dashboard was built with AI assistance. Every number is fetched live from the public feed named on its tile — nothing is stored, modeled or adjusted by this page, with one labeled exception: the air-quality tile is a model estimate, not a physical sensor, and is marked as such.
Feeds go down, lag or report bad values; each tile shows its own "as of" time and goes gray when its feed is stale or unreachable.
Readings here are for curiosity. For emergencies and safety decisions, rely on official channels.
Spot-check anything you plan to rely on. See the methodology for every endpoint, refresh cadence and known caveat.

Subway trains are counted on the board but not mapped — the public train feed reports positions by track segment, not coordinates. Weather radar is imagery, shown in its own panel below.
