“precipitationAmount”

HI there, when requesting the daily forecast via the WeatherKit REST API, I found out that under certain circumstances the moon phase full is skipped. Example from Japan (working): { forecastDaily: { name: DailyForecast, metadata: { attributionURL: https://developer.apple.com/weatherkit/data-source-attribution/, expireTime: 2024-10-21T15:16:10Z, latitude: 35.650, longitude: 139.840, readTime: 2024-10-21T14:16:10Z, reportedTime: 2024-10-21T12:00:37Z, units: m, version: 1, sourceType: modeled }, days: [ ..., { forecastStart: 2024-10-16T15:00:00Z, forecastEnd: 2024-10-17T15:00:00Z, conditionCode: MostlyCloudy, maxUvIndex: 4, moonPhase: waxingGibbous, moonrise: 2024-10-17T07:47:26Z, moonset: 2024-10-16T20:09:01Z, precipitationAmount: 0.09, precipitationChance: 0.43, precipitationType: rain, ... windSpeedMax: 16.03, }, { forecastStart: 2024-10-17T15:00:00Z, forecastEnd: 2024-10-18T15:00:00Z, conditionCode: Rain, maxUvIndex: 4, moonPhase: full, moonrise: 2024-10-18T08:20:34Z, moonset: 2024-10-17T21:24:49Z,

I've received a forecast with non-zero precipitationChance and zero precipitationIntensity. Is this expected? How should I interpret the data? { forecastStart: 2023-09-02T02:00:00Z, cloudCover: 0.55, conditionCode: PartlyCloudy, daylight: false, humidity: 0.92, precipitationAmount: 0, precipitationIntensity: 0, precipitationChance: 0.31, precipitationType: clear, pressure: 1017.56, pressureTrend: steady, snowfallIntensity: 0, snowfallAmount: 0, temperature: 12.56, temperatureApparent: 12.22, temperatureDewPoint: 11.26, uvIndex: 0, visibility: 23505.2, windDirection: 233, windGust: 6.17, windSpeed: 2.82 }

At the moment (8:30 PM), for a number of counties in my area, WeatherKit is indicating a conditionCode of WintryMix for overnightForecast. The low is above freezing, and according to the iPhone weather app there is zero percent chance of precipitation overnight. WeatherKit shows a 0.36 (36%) chance of precipitation but 0 precipitationAmount and 0 snowfallAmount. No other weather data I can find indicates any precipitation overnight in this area. In fact it's supposed to be clear overnight. For now, as an immediate fix, I'm using the restOfDayForecast to get me to midnight, as it seems to be correct. However this is extremely concerning, and my users are very concerned (we're in a fairly southern area) because of this totally false WintryMix conditionCode. I'm really not sure what to do about this. Maybe ignore the condition code if it indicates precipitation but with a 0 precipitationAmount? I'd also like to know why the iPhone weather widget is correct but this WeatherKit data is not. There

I'm in Changsha, China. get my current location from Apple Maps. but the WeatherKit result is not same with Weather App. request: GET /api/v1/weather/zh-CN/28.212151/112.955606?countryCode=cn&timeZone=Asia%2FShanghai&dataSets=forecastHourly&hourlyStart=2022-12-12T22%3A19%3A05Z&hourlyEnd=2022-12-17T22%3A19%3A05Z host: weatherkit.apple.com response: { forecastStart: 2022-12-17T22:00:00Z, cloudCover: 0.01, conditionCode: Clear, daylight: false, humidity: 0.65, precipitationAmount: 0.0, precipitationIntensity: 0.0, precipitationChance: 0.0, precipitationType: clear, pressure: 1036.48, pressureTrend: falling, snowfallIntensity: 0.0, snowfallAmount: 0.0, /// this is -2.83°C temperature: -2.83, temperatureApparent: -3.64, temperatureDewPoint: -8.47, uvIndex: 0, visibility: 18656.25, windDirection: 318, windGust: 9.61, windSpeed: 4.08 } Weather App temperature is 2°C

In XCode 14.1 beta 3, the HourWeather item precipitationAmount is missing. Is this a bug that will be fixed or a planned change? Without precipitationAmount, the API is almost unusable.

Hi, i've been playing with WeatherKit for the first 3 betas but each time I try to get the UV Index of a forecast I've got 0 as value. For example the hourly forecast of San Francisco at the time of writing is the following : Optional(WeatherKit.HourWeather(date: 2022-07-06 14:00:00 +0000, cloudCover: 0.98, condition: Drizzle, symbolName: cloud.moon.rain, dewPoint: 21.87 °C, humidity: 0.95, isDaylight: false, precipitation: rain, precipitationChance: 0.44, precipitationAmount: 0.44 mm, snowfallAmount: 0.0 mm, pressure: 1000.93 mbar, pressureTrend: Steady, temperature: 22.67 °C, apparentTemperature: 24.89 °C, uvIndex: WeatherKit.UVIndex(value: 0, category: Low), visibility: 8977.97 m, wind: WeatherKit.Wind(compassDirection: South Southeast, direction: 151.0 °, speed: 32.34 km/h, gust: Optional(48.66 km/h)))) While the UV Index at the time from The Weather Network is supposed to be 4. I've got this issue since beta 1 and it's happening on every location I try. Is this happening as well to other people

I've been getting at the precipitationAmount data using this hack from another thread. I've often found that the precip amount is 0mm for every hour of the day. Every entry for today has the same precipAmount of 0mm: HourWeather(date: 2022-06-27 22:00:00 +0000, cloudCover: 0.15, condition: Mostly Clear, symbolName: sun.max, dewPoint: 12.43 °C, humidity: 0.78, isDaylight: true, precipitation: , precipitationChance: 0.0, precipitationAmount: 0.0 mm However the iOS 16 beta 2 weather app is showing precip data for today at the same location. Is the iOS 16 Weather App using the same WeatherKit as I am? I'm finding the data in weatherkit to be pretty different than the data in the weather app.
