In December and January, San Francisco Bay will see king tides, extreme tides caused by three colliding factors: the Sun and moon aligning—a full moon—while both are at their closest points to Earth. However, the sea level in the Bay is constantly rising, and today’s king tides could be tomorrow’s regular high tides. Learn more about king tides and how sea-level rise will impact the Bay Area, as well as how local groups are planning for shifting shorelines and envisioning a more resilient future.

Program features:

What causes the extraordinarily king tides that happen in November, December, and January? Join the Exploratorium's Ron Hipschman as he shares the science behind king tides in this Full Spectrum Science Short.

Get an overview of the California King Tides Project with Annie Frankel from the Public Education Program at the California Coastal Commission. Find out how you can participate and further our understanding of king tides.

How do artists approach the problem of sea level rise and its impacts on infrastructure? Explore the art/science dialogue facilitated by the Exploratorium's Fisher Bay Observatory Gallery through the project Artistic Practice for Urban Resilience (APUR). The project connected two artists with a scientific research program called Resilient Infrastructure as Seas Rise (RISER) with the goal of expanding the conversation about sea level rise and its impacts on regional infrastructure.

How can we track, map, and understand the rise of the Bay? Join Bay Conservation Development Commission (BCDC) team members Todd Hallenbeck and Samantha Cohen for a discussion of the work of the recently established BCDC program Adapting to Rising Tides. The project integrates Bay Area sea level rise and shoreline analysis maps to build tools for assessing rising tides, identifying risk, and analyzing future scenarios.

Learn about the People’s Plan in Marin City—led by Pandora Thomas—which brings local residents and communities into the process of developing resilient solutions for addressing sea level rise in their region.

The movements and mechanics of the planets, moons, and stars create awesome effects for us observers on Earth. Predictable yet coincidental, these cycles among the stars lead to gravitational bulges, lunar alignments, and a turnaround of apparent motion. Join us this month as we explore these effects as opportunities for wonder and harbingers of future change.
