Expert weather and climate analysis for high-stakes decisions.
Weather and climate data are easy to access. Knowing which data are reliable, what they mean, and how they should be used is much harder.

Degree Day provides independent advisory and research support for utilities, investors, infrastructure owners, asset managers, data teams, and other organizations facing weather- and climate-sensitive decisions that generic datasets, dashboards, or vendor outputs cannot answer.
We work across observations, reanalysis, forecasts, climate projections, and hazard models to develop clear, balanced, technically defensible analysis.
- Observations
- Reanalysis
- Forecasts
- Climate projections
- Hazard models
When to Use Us
You should talk to us when:
-
A dataset, forecast, model, hazard map, or vendor output does not add up - You need to know whether weather or climate data are fit for a specific decision
- You need analysis tailored to a nonstandard weather or climate question
- You need to understand how unusual an event is
- You need defensible climate assumptions for planning, due diligence, or risk review
- You have money, infrastructure, operations, or credibility riding on the answer
What We Help With
Data Fitness & Method Review
We evaluate whether observations, reanalysis, forecasts, climate projections, or vendor outputs are appropriate for the question at hand.
Example questions:
- Which dataset is most reliable for this region, variable, or hazard?
- Why do two products disagree?
- Does downscaling or bias adjustment solve the relevant problem?
- Are the assumptions and limitations defensible?
Weather & Event Analysis
We help clients interpret recent, emerging, or forecasted weather events in historical context and understand where they may matter.
Example questions:
- How unusual is this heat wave, cold snap, drought, wind event, or rainfall event?
- Which historical events are useful analogs?
- Which assets, markets, or regions may be affected?
Custom Analysis & Decision Support
We help clients turn complex weather and climate questions into practical analytical inputs when standard datasets or off-the-shelf products are not enough.
Example outputs:
- Bespoke weather or climate metrics for a specific decision
- Event studies and historical analog analysis
- Dataset and vendor comparison memos
- Exposure screens for assets, portfolios, or regions
- Technical review of climate assumptions, methods, and limitations
- Research memos for nonstandard weather or climate questions
- Briefings for executives, investors, regulators, or project teams
Climate Planning & Risk Research
We help clients interpret climate projections, hazard data, and uncertainty for planning, due diligence, and risk review.
Example questions:
- Which climate assumptions are appropriate for this decision?
- Which datasets or models are credible for this region and hazard?
- What does uncertainty mean for the decision?
- Are existing climate-risk outputs technically defensible?
- Which assets, regions, or assumptions require deeper review?
Who We Support
- Utilities and energy companies
- Investment and research teams
- Infrastructure owners and asset managers
- Insurers, lenders, and investors
- Data teams and climate/weather vendors
- Public agencies and project teams
What You Get
Clear Technical Judgment
We help determine what the data can support, where uncertainty matters, and where conclusions would be overstated.
Custom Analysis
Engagements can include research memos, custom datasets, event studies, exposure analyses, model reviews, planning assumptions, or recurring advisory support.
Transparent Methods
Data sources, assumptions, methods, limitations, and uncertainty are documented clearly.
Decision-Ready Outputs
Deliverables can include technical memos, executive summaries, charts, tables, GIS layers, CSV files, model inputs, and client-ready methodology language.
Why Degree Day
Degree Day is independent by design and evidence-first. We flag serious risks when the data support them — and we say so when a dataset is weak, a model is not fit for purpose, or a conclusion goes beyond what the science can justify.
We start with the decision, the data, and the limits of the evidence — not a narrative.
