A strange iPhone Weather app forecast in Hangzhou, China, briefly showed temperatures approaching 50°C, prompting local weather officials to issue a clarification. The Lin’an District Meteorological Bureau in Hangzhou said the extreme forecast came from an app-side data error, not from official meteorological data.
The issue appeared on the evening of June 7, when users of a well-known smartphone brand’s built-in weather app saw forecasts for Lin’an District on June 15 showing unusually high temperatures. Some screenshots showed highs around 48°C or 49°C, while other users reported readings above 50°C.
According to the local bureau, neither its office nor higher-level meteorological departments had issued any forecast suggesting nearly 50°C heat over the next 15 days. The official forecast from China Weather for Lin’an on June 15 was far more normal: a high of 32°C and a low of 21°C.
The bureau advised users to rely on official sources such as China Weather and local meteorological stations when a phone weather app shows a forecast that clearly does not match local climate expectations. In other words, dramatic app readings should be treated carefully until confirmed by an authoritative forecast provider.
IT Home found that multiple users had shared screenshots from Apple’s built-in weather app, showing Hangzhou’s Lin’an District with forecast highs close to 50°C and in some cases as high as 54°C. That led the incident to be discussed as an Apple Weather data problem rather than an actual heat warning.
Apple’s own support information says that, unless otherwise noted, 10-day forecast data in the Weather app is provided by Apple Weather. The incident is a reminder that even default phone apps can occasionally surface incorrect or inconsistent forecast data.
For iPhone users, the practical lesson is simple: if the iPhone Weather app suddenly shows an extreme forecast that seems out of line with surrounding cities or official alerts, it is worth checking another trusted source before assuming the reading is real.
There is no indication from the local meteorological bureau that Hangzhou’s Lin’an District was actually expected to face near-50°C temperatures on June 15. The clarification identifies the problem as a software or data-system error on the app side.
