CNET compares Alexa Plus, Gemini for Home and Siri AI on weather accuracy
A CNET reviewer spent several months testing Amazon's Alexa Plus, Google's Gemini for Home and Apple's Siri AI for weather forecasting accuracy in a high-desert city with microclimates. The test found Alexa Plus gives the longest, most detailed responses—including wind, air quality and 'feels like' temperatures—but occasionally mispredicted rain and tended to overestimate high temperatures.
GoKawiil's interpretation of the reporting above, not reported fact.
The comparison suggests that voice assistants draw on different data sources and algorithms, which can lead to meaningfully different forecasts for the same location, according to the reviewer's testing. This could matter to users who rely on these assistants for daily planning, since verbosity and detail don't necessarily correlate with accuracy.
- CNET tested Alexa Plus, Google Gemini for Home and Siri AI for weather accuracy over several months.
- Alexa Plus provides the most detailed, chattiest weather reports but sometimes overestimates highs or predicts rain that doesn't occur.
- The test location's microclimates and federal cuts to weather stations were cited as factors making it a challenging testbed.
Amazon Echo Dot (5th Gen) — Since Alexa Plus is one of the assistants put through the wringer in this weather showdown, the Echo Dot is the easiest way to test its forecasting chops yourself. It's a compact, affordable smart speaker that makes asking for daily weather updates as simple as speaking into the room.
