Degree Day LLC

Degree Day is a consultancy that assesses how extreme weather and climate change impact assets, operations, and supply chains. We partner with businesses, engineers, utilities, asset managers, and governments to support risk management with quantifiable benefits. While climate data are a key aspect of our work, we also integrate diverse evidence and expert judgment. Through a hands-on, research-driven approach, we deliver practical, actionable insights tailored to organizations. We believe that physical climate risks require expert navigation. Data alone will fail to drive meaningful action, as climate model outputs are inherently limited. That’s why we take a tailored, evidence-based approach, interweaving multiple sources of data, contextual knowledge, and expert judgement to provide organizations with a comprehensive understanding of risk. We are committed to equip decision-makers with transparent, actionable, and practical weather and climate intelligence—helping them make informed choices in an uncertain and rapidly changing world.
