Is Today a Heat Strike Day?

A Heat Strike Day is any day when your forecast high exceeds the 99ᵗʰ percentile of historical highs for that date. On those days, we invite you to take a simple but powerful stand: pause business-as-usual by limiting your economic activity. Delay nonessential tasks, skip major purchases, and devote your time to rest, caring for others, or supporting climate action in your own way.

Why It Works

Every dollar you spend and every hour you work keeps the economy running—even as climate instability threatens our future.
On Heat Strike Days, our collective pause declares: “If safe temperatures aren’t guaranteed, our participation isn’t either.”
By refusing to participate in business-as-usual, we make climate inaction their problem and force companies and governments to change course.

How to Participate

1. Check today’s forecast each morning.
2. If your expected high exceeds the 99ᵗʰ percentile threshold, it’s a Heat Strike Day.
3. Pause nonessential activity:
   • Delay shopping and errands
   • Skip optional work and meetings
   • Rest, go outside, or organize for change

A New Kind of Climate Action

Heat Strike Days aren’t about guilt or perfection—they’re about speaking up when “normal” breaks.
The more of us who join, the louder our message: companies and decision-makers take notice when we pause together.

Spread the Word

Tell your friends. Post the forecast.
You don’t have to do everything to confront climate change. But on a Heat Strike Day, doing less can still be a powerful act.
