# wnd\_ave This value is calculated by summing the average or mean wind speed values for every day in the month for all years of record and dividing the sum by the number of days: $$ μwnd\_{mon}=\frac{∑*{d=1}^N\*T*{wnd,mon}}{N} $$ where $$μwnd\_{mon}$$ is the mean daily wind speed for the month (m/s), $$T\_{wnd,mon}$$ is the average wind speed for day $$d$$ in month $$mon$$ (ºC), and *N* is the total number of daily wind speed records for month $$mon$$. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://swatplus.gitbook.io/io-docs/introduction-1/climate/weather-wgn.cli/wnd_ave.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
