What Is the
Wired Pier?

The Wired Pier is an array of sensitive instruments around the Exploratorium campus at Piers 15 and 17, measuring and recording conditions in the environment—the weather, Bay water, pollution, and more. We're displaying the live data on this website and in the Fisher Bay Observatory Gallery. We're also archiving the data so that the public and our scientific partners can explore patterns and trends in the atmosphere, oceans, and urban landscape.

Data Story: Tide Cycles at Pier 15

You’ve seen high and low tides at the beach. Get to know the daily and monthly cycles of the tides, why they change every day, and how they affect San Francisco Bay.

Data Story: Tides and Salinity

See how the salinity, or saltiness, of Bay water rises and falls with the tides, and what many years of salinity data reveals about California’s climate.

Activities with Data

Learn more about the natural processes behind the numbers. These do-it-yourself activities let you try things like building a device to measure the saltiness of water, or learning about the link between gravity and tides.

Smoky air creates vivid sunrise in the Bay Area.
With Fall Comes Easterly Winds, Fires and Smoke in Northern California

by Mary Miller • October 18, 2017

Fall, not summer, is fire season in California. The aftermath of rainless but foggy summers and a shift in the winds that normally bring cool, moist air from the Pacific but instead blow from the dry, warm interior create the perfect recipe for fires. That weather pattern exploded this October into deadly wildfires that affected air quality all over the Bay Area.
