Google is testing a generative AI weather summary to enhance user experience for weather updates, providing a comprehensive overview between hourly and 10-day forecasts. This feature is currently limited to Southern California, including cities like Los Angeles, San Francisco, and San Diego, and is accessible only to users signed into their Google accounts via the Google app and mobile web searches. It does not extend to the Google Weather app. Additionally, the Pixel Weather app has introduced a pollen tracker in the U.S., featuring a five-day view of pollen levels and insights into seasonality and cross-reaction data.
