Why water security matters to cities under extreme heat in the Global North.

Household water security - safe, affordable, reliable, and acceptable water for a thriving life - is a key avenue for adapting to extreme and chronic heat, particularly in cities. We argue that household water security is far from universal in the urban Global North, resulting in uneven capacities and strategies to adapt to heat, outside and within the home. We synthesize key insights to advance water security as a central plank of urban heat justice.
