Acurite HD Weather Station Forecast is very wrong

  • Updated 3 weeks ago
I bought the HD Weather Station on Jan 16th 2017 and now its been roughly 2 months since I've owned it. Despite it running through the calibration phase, I've noticed that the forecast is almost always wrong. I understand how it works as I'm a meteorologist, it goes off pressure tendencies and lately here in Amarillo,TX...all the storms are missing us. So while we may go through an insane pressure drop due to a nearby low pressure system developing we get winds not rain. The few times we've gotten snow it says clear and never said snow prior to the day...seems pretty inaccurate to be honest, contemplating asking for a refund.

Hello Cameron,

If you are getting an incorrect forecast reading, we would recommend restarting your display by unplugging it for about 2 minutes. You want to do this when the local pressure is reading 29.92. Power the weather station back up, and let it go through the 14 day learning mode. Once the learning mode is complete you should get an accurate future forecast reading.

Alright...I'm moving in 2 weeks so I might as well start over with the calibration at my new apartment. Ive noticed that it seems like its still off by inches of Hg. My station is saying 30.00in while the NWS and many other reliable local sources say 30.10in. I started the calibration back on Jan 31st 2017 so its say to say it should be calibrated.

0.10 inHg is not a big difference.  What you are really interested in is the pressure trend.

That is true but its always predicting rain...I wouldn't say 30.00in should call for rain especially with a rising trend....just seems inaccurate I was hoping it would be a little better but alas that seems that is not the case.

Mine also always says rain. We haven't had rain in over a month. Maybe my station is too close to our herb garden. We just use it for temp, wind, and rain total and just keep joking that it's going to rain again.

Hello Janet,

Your display does go through a 14-33 day learning mode that does affect the forecast, and pressure readings. Is the learning mode complete on the weather station? If it is then we would recommend restarting the display when your local pressure is at 29.92. You would remove all power for about 2 minutes, and start the weather station back up again. This will initiate the learning mode again. Once the learning mode is complete, you should have an accurate pressure and forecast reading.

Oh really? How does this effect that the 01604 ALWAYS reports ridiculously WRONG temperatures!?? Is that part of a "14-33 day learning mode"?? I've had the 01604 for 6 months now, purchased new and compared to a calibrated Liquid Mercury out doors thermometer near it shaded from direct sun, the 01604 is WRONG in the mornings with 10 to 12 degree + spikes when the sun is on it to being wrong - 5 to 8 degrees in the evenings in the shade. Also, the forecasts are as other have stated, WORTHLESS. This is a worthless Weather Station for every function. Even wind speeds are wrong measured against a $200 Anemometer. Oh, PS - we're in So Cal and the station has frequently, but not every day, forecasted "Rain and Thunderstorms" with not a cloud in the sky. 411 even at the coast we don't get any rain from May to October.

Hello Cameron,

We do have an accuracy standard for our barometric pressure. The reading will be accurate within +/- 5hpa. 

The accuracy range will be within +/-0.15inHg (+/- 5mbar). For instance, if the current relative air pressure is 29.92inHg, then the unit could read within the range of 29.77inHg to 30.07inHg. I would still recommend restarting the display when your local pressure is at 29.92. Thank you.

Alright I'll reset it when I move in 2 weeks. Hopefully that fixes the trending forecast. 
Thanks for your time!

Hi Jennifer, I reset my display when it was reading 29.92 when it rebooted it read 25.06 is this ok? Will it self adjust?

As long as it entered the "learning mode", you will be fine.  it's not necessary to start it at 29.92, but it does make the resulting changes somewhat easier to follow with the eye.  Otherwise, it will all work out mathematically.

Thanks. I just rebooted again and it came up 29.92.

It/s working as it should.  You should see reliable pressure measurement startling in about 2 weeks and getting better for 4.
