NEW for 2025!
WXSim is a unique and complex weather simulation application developed over many years by Thomas J. Ehrensperger. Its primary purpose is providing accurate and detailed forecasts tailored for a specific location, using a combination of imported real-time and model data from a range of sources plus data from a local weather station, along with its own internal modelling capabilities. Over time it uses machine learning to improve forecasts from past results. Tom provides extensive local customisations when the application is purchased, which includes geographical and historical climatological data, ground cover, water bodies, diurnal temperature range and overall temperature bias, to name just a few.
It is an extensive application that ingests a huge amount of data from online services such as GFS, ECMWF, RAOB soundings (upper air), advection data such as METAR, synoptic and buoys, and of course our own weather observations.
The forecasts can be generated manually or fully automated. Our forecasts are currently fully automated, and use machine learning to improve temperature, dewpoint and wind forecasts to improve accuracy based on observation data.
This page is based on the European Weather Network format and is divided into several sections: the top shows the date and time of issue, next update, and the forecast for the next hour, you can also change the display units on the top right The next row shows a compact iconic forecast for the next six days. Below the icons are three tabs, Overview, Table and Graphs: The overview tab shows a detailed forecast for each day / night; the table shows the expected hourly conditions for each day (click or tap on the day icon to display the table data); and the graph tab shows a graphical representation for each day. You can also show a graph for the full forecast period. See the About page for more information.
