Palm Springs Preps First Extreme Heat Summit as Coachella Valley Bakes in the 110s

Palm Springs has announced the speaker lineup for its first-ever extreme heat summit, a full-day gathering set for Friday, September 18, at the Palm Springs Convention Center, as the Coachella Valley continues to swelter through another round of triple-digit temperatures. The city says recent temperatures have already climbed into the 110s, and extreme heat warnings have been issued across the region this summer.

The event, titled Heat as Infrastructure: Designing Systems, Cities, and Services for Resilience, was organized by the City of Palm Springs Department of Sustainability in partnership with the city's Office of Emergency Management, according to KESQ. Palm Springs Sustainability Director Jasmine Fields said climate projections indicate the Coachella Valley will keep getting hotter, a warning that frames the summit's entire agenda. The city is intended for both professionals and community members interested in preparing for extreme heat, and it is currently recruiting volunteers to help support the event.

Mayor Naomi Soto will deliver the welcome address, followed by a keynote from Diane Morales, Public Policy Lead for the Blue Zones Project, per the City of Palm Springs. Featured speakers include University of Arizona Heat Resilience Initiative Director Dr. Ladd Keith, HARC CEO Dr. Jenna LeComte-Hinley, and Southern California Edison Senior Advisor Anuj Desai. Registration for the summit is currently open, and organizers say it will feature specialists in climate resilience, public health, emergency management, and urban planning.

Four Panels Tackle Heat as a Structural Problem

The daylong program, running from 8 a.m. to 5 p.m., includes registration, welcome, and keynote agenda entries, according to the event listing on Eventbrite. The event's focus is heat resilience, framing heat less as routine summer weather and more as a hazard that can strain systems.

That framing tracks with Dr. Keith's own research portfolio. He is involved in the University of Arizona's heat-resilience research and co-leads the federal Center for Heat Resilient Communities; programs he led or co-led were funded by the U.S. Department of Energy, NOAA, and the CDC, according to the University of Arizona. His involvement signals that the Palm Springs event is drawing on national academic and federal heat-research infrastructure rather than treating the issue as a purely local weather concern.

A Valley Already Living Through Record Heat

The urgency behind the summit is rooted in recent history. Palm Springs hit an all-time high temperature of 124°F on July 5, 2024, breaking a previous record of 123°F, per SFGATE. That same year, the city logged an all-time annual record of 78 days at or above 110°F, the most ever recorded in a year. The Coachella Valley continues to experience periods of dangerous summer heat, and this year's warnings suggest that trend is holding steady rather than easing.

The stakes extend to the power grid itself. Southern California Edison limits scheduled maintenance outages to a maximum of five hours once desert temperatures reach 105°F, and cancels non-emergency maintenance outages entirely above 113°F to avoid cutting air conditioning during dangerous heat, according to Edison's own account on Energized by Edison. Those constraints illustrate why a Southern California Edison advisor is on the summit's speaker list alongside public health and urban planning experts — keeping the lights and air conditioning on during a heat wave is its own infrastructure challenge.

Health Data and Neighborhood-Level Cooling Efforts

HARC is represented at the summit by its CEO, Dr. LeComte-Hinley, who is slated to speak.

At the neighborhood level, Blue Zones Project Palm Springs is identified on a summit page, per Desert Health News. Blue Zones Project policy lead Diane Morales is delivering the summit's keynote address, tying that participation directly to the day's programming.

Cooling centers are mentioned as general advice for extreme heat. The summit's program addresses the broader challenges of heat resilience.

Part of a Broader State and Regional Push

Palm Springs' summit is part of a broader conversation about extreme heat and climate resilience. The gathering positions heat as an infrastructure priority. With registration open and volunteer recruitment underway, Palm Springs organizers are positioning the September 18 gathering as the start of an ongoing regional conversation rather than a one-off event.
