Plan the day with confidence with your own weather station and weather prediction information with pinpoint accuracy right from your own backyard. The AcuRite 01121M Wireless Color Weather Station uses patented Self-Calibrating Technology to provide your personal forecast of 12 to 24 hour weather conditions. Self-Calibrating Forecasting is generated from weather data measured by a sensor in your yard - giving you the most accurate forecast available for your exact location.

The bold, easy to read illuminated color LCD screen includes indoor/outdoor temperature and humidity with daily high/low information, heat index, dew point, barometric pressure, atomic clock and calendar. You may custom program temperature and humidity alerts to notify you when a value has been reached or exceeded. Display stands upright for a tabletop/desk or may be mounted on a wall. The wireless outdoor sensor features a thermometer and hygrometer. One-year limited warranty. It's more than accurate, it's AcuRite.

5 stars Works well for me.
So far so good.

4 stars so far so good
Bought this because it displays the dew point, though I've read it shows heat index when it gets about 80. Not wild about that if true. Pleased with it so far.

4 stars AcuRite Wireless Color Weather Station Review
Nice display and weather data displayed seems very accurate. Only issue so far is that the atomic time feature loses the correct time every day so I switched it off.

5 stars Pleased with new weather station
We are enjoying our new AcuRite Weather Station. Its large numbers and uncluttered appearance are perfect for us. The ordering and from WeatherShack was smooth, and the delivery arrived a day early. So far, so good!

5 stars Perfect for my needs
This device is exactly what I needed to place in the TV cabinet. It looks sharp and has all the data I want. It was easy to set up. It's one of the few products I've viewed that is backlit so you can see it at night. I have had many comments from friends about how nice it looks. Good price, too!

3 stars Nice BUT!!!!!!
With batteries installed for backup - in a power failure, unit goes back to zero and I have to wait hours for time and temperature! What's the purpose of battery backup?

5 stars Nice product, like that it includes dew point
I picked this device because it displayed the dew point. The only thing I'm a little disappointed about is that the when it is hot, the dew point is replaced by the heat index. I wish there were a way to keep the dew point displayed at all temps.
