iPhone users in the UK have received an update to the built-in Weather app, it now supports next-hour precipitation readings, a feature that appears to have rolled out recently.
Next-hour weather details have been available in the United States since the launch of iOS 14, but the feature had not expanded to other countries prior to this week. The new precipitation charts appear to be showing up for those running both iOS 14.2.1 onwards.
Apple added next-hour precipitation to the Weather app after its acquisition of Dark Sky in March 2020. Precipitation charts improve the accuracy of the wearer app by offering minute-by-minute weather predictions depending on the location being supported.
