Wind gusts on WU and My AcuRite

Since I’m fairly new to acurite can someone explain to me in simple terms how I can have my wind gust show up on My AcuRite and weather Underground. I don’t have a smart hub if that means anything. Thank you for any help and the time to read this post

Unfortunately it's kind of complicated...

myAcurite doesn't post any "gust" data.  It does show "high winds", but that's not technically the same thing as a "gust".  I can't really explain why myAcurite does not give you this information.

As far as wunderground goes, it calls a "gust" whatever your reporting software decides to call a gust.  

If you have a SmartHUB, it's using a very strict National Weather Service definition of a "gust".  I assume PC Connect is also using the same "gust" definition, but I'm not sure.

Anyway, the NWS definition is this:

Wind Gust
A sudden, brief increase in the speed of the wind followed by a lull. Gusts are reported when the peak speed reaches at least 18 mph (30 km/h) and the variation in wind speed between peaks and lulls is at least about 10 mph (17 km/h).
The "problem" with this definition is that it is very strict and often does not generate any "gust" markings on the wunderground graphs.  It will if the conditions are met, but often they are not, such as the minimum 18 mph speed.

Many reporting to wunderground, however, are using a very lax definition of gust.  For example, they'll label a gust as the fastest wind speed in the past 6 or so minutes.  This results in a lot of "gust" markings on the graphs, many of which are really silly.  (I have trouble calling a 1 mph wind a "gust" for example).

Because of the lax definition of many, and the strict definition used by Acurite, people think something must be "broken" on the Acurite side, even though it's working perfectly fine.

I suspect Acurite will eventually "give in" and start using a looser definition of "gust" just to keep up appearances on wunderground.

So, in short, you really don't have to do anything on your end.  myAcurite isn't going to plot gust anyway, and the SmartHUB (and I assume PC Connect) are currently using the strict NWS gust definition on wunderground.

George's reply sounds good enough for me to by it thanks George. I had not paid attention to the hardware that was showing the gust on wunderground.

I'm having a hard time following the "gust definition" explanation.  My station KILSPRIN80 does not report gusts on Weather Underground.  Stations near me KWIWILM02, KILSPRIN55, KWITWINL6 all report wind gusts, even today with wind 2-4 and showing gusts 4+, either on the summary screen or in graph form.  At least in my case it does not appear to be a problem with the definition of a gust.  Is there something else I need to set up?  I'm using pc connect on Windows 10.  The gusts show fine on the monitor in the house  model 02032 weather station mounted 12 feet off the ground on the grass.

"Gusts" are defined by the software or firmware that is doing the reporting.

Stations around you showing low speed winds as "gusts" are using a very loose definition of "gust" which borders on nonsense.  Unfortunately, that's what is popular these days.

There's nothing you can do to change gust reporting short of replacing PC Connect with some other software package with a looser gust definition.

Hello Bob,

The wind gust that reports to Weather Underground is going to be the highest wind speed reported within the last 5 minute interval. The wind speed will be the last wind speed reading reported at the last 5 minute interval. Please let us know if there is anything further we can assist you with.
