Plan the day with confidence with your own weather and weather prediction information with pinpoint accuracy right from your own backyard. The AcuRite 00638 Wireless Weather Station with Wind Speed 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 LCD screen includes indoor/outdoor temperature and humidity with daily high/low information, heat index, wind speed, wind chill, multi-variable history chart, moon phase, radio-controlled clock and calendar. Clock and calendar are radio-controlled to maintain the correct time and date with split-second precision, and automatically adjust for daylight saving time (DST). Display stands upright for tabletop use or is wall-mountable. The wireless outdoor sensor features three different technologies in one easy-to-mount unit: thermometer, hygrometer, wind speed anemometer. One-year limited warranty. It's more than accurate, it's AcuRite.

4 stars A decent product for its price
I personally would prefer the option to switch from showing the dewpoint to heat index versus it automatically switching once the air temperature reaches 80°F.

5 stars It works
It seems to do those things I want it to do

5 stars Love the weather reader.
I really like it. We have had one before. We don't need to look at our big round thermometer outside anymore. We are older and it is better for us. We can just sit in our chair and read it. Thanks

3 stars Good but no backlight can't see it at night.
We like it. Wish we had gotten a rain gauge with it...does not come with all the batteries needed, also no backlight so at night when you want to check weather have to turn a light on.

WEATHERSHACK STAFF UPDATE This model does not come with batteries. The customer purchased lithium batteries for the outdoor sensor only; as explained on the product's webpage.

5 stars Excellent product for the price
I purchased this weather station to replace one that had broken (outside unit). I was pleased when I installed the new outside unit that both of my inside units would receive data from the outside unit. I now have one both in my office and bedroom with only one outside unit.

5 stars Great Weather and Wind Center.
We got this to measure not only the temp outside, but the wind chill. It was easy to set up and works great. It hangs on our way under our clock.

It is delightful to sit at my dining table and see what the weather is outside so I know how to dress for the day. Especially helpful if I intend to go outside and work. Thanks for a great product that works really well......
