Future Weather transforms historical weather files into future climate-adjusted files (EPW, and optional DDY/STAT) in less than 30 seconds. The platform takes a baseline EPW file and applies the latest (CMIP6) climate change projections through a morphing process—adjusting temperature, humidity, solar radiation, and other variables to reflect future conditions while preserving realistic hourly weather patterns. The result is a physically consistent weather file representing conditions at a specific future time period.
The morphing methodology is based on published research developed by Dr. Eugénio Rodrigues at the University of Coimbra, and we've added a number of platform enhancements on top of that foundation. The platform supports 23 CMIP6 global climate models across multiple SSP scenarios, with flexible time period selection and model ensemble averaging. Files are generated through a web interface or API and are compatible with EnergyPlus and leading commercial building and HVAC design tools that accept EPW/DDY/STAT formats.
Typical applications include HVAC load calculations under future design conditions, whole-building energy analysis for climate adaptation planning, and thermal resilience assessments. The platform is designed for engineers, architects, and researchers who need standardized future weather data for technical analysis and regulatory compliance.
Create climate‑adjusted EPW, DDY, and STAT files in under 30 seconds for any location, climate scenario, and future period, using a full ensemble of 23 climate models or a combination of your choice.
Built in partnership with Dr. Eugénio Rodrigues, creator of the original Future Weather Generator, which is described in a published paper with more than 145 citations.
Built with a modern API-centric architecture and webhook support, ready for integration with simulation software, enterprise workflows, or batch jobs.
Select a location, upload your EPW file, pick a future period, climate scenario, and climate model(s).
We run your EPW file through our morphing pipeline and incorporate climate data to adjust each variable.
Download your files (EPW/DDY/STAT) immediately or come back and download them later.

Learn More & ApplyRowan Schmidt, Head of Product at FutureWeather.co, was invited to present FutureWeather.co to ASHRAE Technical Committee 4.2 (Climatic Conditions) in February 2026. The session was a technical, non-commercial presentation focused on the methodology, product, and future weather generation workflow.

Download Presentation PDFFutureWeather.co is now available as a Dynamo package for Autodesk Revit users who want to generate future climate-adjusted EPW and DDY files directly from Dynamo. The package connects to the FutureWeather.co API in the cloud, with support for single jobs, batch workflows, authentication, and result downloads.
This makes it easier to bring future climate weather files into BIM, energy modeling, HVAC sizing, and thermal comfort workflows without leaving the Revit environment.

By combining data, technology, and domain-specific expertise, we aim to empower government agencies, communities, and private sector organizations to make informed decisions, optimize resource allocation, and effectively pursue economic development and resilience strategies. Radbridge develops and operates the Future Weather platform.
The CURA Lab team, led by Eugénio Rodrigues, brings together a multidisciplinary group of researchers and graduate students with backgrounds in architecture, urban planning, civil engineering, and mechanical engineering. This diversity of expertise enables us to address the complex challenges of climate change, urban resilience, and the urban heat island effect from multiple perspectives, integrating technical, design, and policy-oriented approaches. The team is further supported by an international advisory panel of leading scholars.
Our platform uses a scientifically-validated "morphing" methodology to combine high-quality historical weather data with future climate projections from the latest IPCC AR6 (CMIP6) global climate models. This process adjusts variables like temperature, humidity, and solar radiation to create a plausible future weather file that reflects long-term climate change signals while maintaining realistic, minute-to-minute weather patterns.
We stand apart in three key ways. First, we use the most current climate science, leveraging IPCC AR6 (CMIP6) projections, while many older tools rely on the previous AR5 generation. Second, our cloud-native platform is built for speed, generating files in minutes via a web UI or API. Finally, our unique collaboration with the academic creator of the original Future Weather Generator ensures our methodology is both transparent and rigorously validated against the established standard.
We support a range of future scenarios from the IPCC's AR6 report, including the commonly used SSP2-4.5 (medium emissions) and SSP5-8.5 (high emissions). You can generate weather files based on an ensemble of 23 different Global Climate Models (GCMs) for a robust average projection, or select specific models to test for a wider range of potential outcomes.
Absolutely. Our platform generates files in standard, industry-recognized formats. The primary output is the EPW (EnergyPlus Weather) file, which is directly compatible with most building performance simulation tools, including EnergyPlus, OpenStudio, IES-VE, TRACE 3D Plus, and others. We also offer optional DDY (Design Day) and STAT files for HVAC sizing and analysis.
Our methodology is published in a peer-reviewed scientific journal and was developed in partnership with the method's original creator. We perform extensive side-by-side comparisons to ensure our outputs match the results of the original, validated research tool. Furthermore, every generated file undergoes automated quality assurance checks to verify that data is physically plausible and correctly formatted.
