  • Weather Data

    Speedwell Weather supplies high-quality historical observed weather data and real time weather data feeds for tens of thousands of sites world-wide.

    Our unique SuperPack® product provides unlimited group-wide access to our entire weather data archive of thousands of data sets and real-time feeds for a single subscription. Our archives cover daily, hourly and sub-hourly data providing both history and real-time feeds. Our clients are companies world-wide in sectors including energy, agriculture, commodity-trading, renewables, retail, insurance and weather risk markets. Speedwell's origins as a weather data provider lie in the weather risk markets where we are the dominant provider of weather data for pricing weather risk contracts and where we are the dominant settlement agent for over-the-counter weather risk transactions.

    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 Forecasts

    Speedwell Weather supplies site-specific ensemble forecasts across the world covering 15-day and monthly 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, agriculture and weather risk markets across the globe.
  • Weather Derivative Software

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

    Available as a hosted application or internally-installed SWS consists of many millions of lines of code representing over a decade of continuous development to produce a tool that provides a consistent and reliable framework for valuing weather hedges, for managing a portfolio of weather risk and for the process of seeing those transactions through all back office stages to final settlement. We have a philosophy of transparency: no black boxes and full documentation of methods. All SWS outputs are easily exportable, and all components are re-usable in 3rd party systems, subject to licence.

    SWSConnect is a web-delivered weather derivative pricing tool based on the same underlying components as SWS. Ideal for pricing CME weather derivative contracts.

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.
