Speedwell Recalibrated Data Sets re-base historical temperature data for important reference sites by adjusting for known or observed discontinuities that have accumulated over the life time of the observations.

Weather Forecast

Speedwell Weather supplies site-specific ensemble forecasts across the world covering 15-day, monthly and seasonal periods.


The ensemble forecast is a probabilistic forecast which inherently captures information that is normally lost in a traditional deterministic forecast.



Forecasts can be delivered both with interactive web-delivered tools and as underlying data. Web-based forecast delivery gives users the ability to view, interrogate, and verify archived forecasts as well as overlay historical data.

Speedwell Weather supplies forecasts to clients in Energy and Weather Derivative Markets across the globe.


Weather Derivative Software

Speedwell Weather supplies the definitive weather derivative pricing and risk management system, the Speedwell Weather System, SWS.


The product of over seven years of continuous development, SWS offers sophisticated pricing tools as well as portfolio management and full back office functionality.



Weather Risk Placement and Consultancy

Speedwell Weather are experts in analysing, structuring and placing weather risk.

In our capacity as a regulated independent consultancy we are able to assist companies in quantifying their weather exposure and then to structure and place such risk with the weather derivative risk-taking community.

Since its establishment in 1999, we have cultivated extensive relationships in the weather risk-taking community amongst all types of participants.
These include insurance companies, banks, energy companies and investment funds. We do not act as principals ourselves and nor are we exclusively aligned to a single principal.
