Hourly history with WeatherKit REST API

Ditto! It respects dailyEnd, but not dailyStart. This query will yield an empty array. Removing dailyEnd will return 10 days of June.

It's probably forthcoming later this summer, but filed FB10383199.

Yeah - we are having the same problems. Can get current weather only but are much more interested in historical.

Lucky you! :) I cannot even get currentWeather. Constantly receiving 401 response.

Same problem here, no way to get the historical data, even though this is advertised. I'm using darksky.net now, which Apple has acquired. Need to port my code to the WeatherKit, and I thought it would be easier with all being on the Apple platform. However, it has has given a lot of headaches so far to try and get everything to work.. :(

Thank you all for the reports. This is a known issue that will be addressed soon.

With the Darksky API, it was possible to get hourly historical weather data of 50 years back. I am struggling with getting the same from the Weatherkit API. Is there an example call that provide e.g. the historical hourly weather data on a specific location, and a date of e.g. 20 years back?

With the Swift API (not REST) I'm still finding it to be hit or miss. Here's a look ...

// Historical daily request let forecast: Forecast<WeatherKit.DayWeather> = try await weatherService.weather(for: location, including: .daily(startDate: november24-2021, endDate: november25-2021))

Yes it is still not working even though iOS 16 has been released in the meantime. Not good :(

request like this can get historic hourly weather conditions, but it's not accurate in my area:

GET /api/v1/weather/zh-CN/28.212151/112.955606?countryCode=CN&timeZone=Asia%2FShanghai&dataSets=forecastHourly&hourlyStart=2022-12-15T23%3A46%3A03Z&hourlyEnd=2022-12-17T23%3A46%3A03Z

Attempting to get a actual weather for previous day (e.g. earlier today) I'm getting a status of 400, error: "Bad Request"

Not sure what I'm doing wrong as I'm using forecastHourly in a GET URL as follows:

'https://weatherkit.apple.com/api/v1/weather/en/37.873377/-122.046918?dataSets=forecastHourly&hourlyStart=2023-02-20T17:00:00+00:00'

Maybe I need to encode the hourly start parameter? [tried that to no avail]

Don't really want to have to pass country code as these items are all over the world. I'm hoping that the lat/lon will be sufficient.

I've also attempted to truncate to the hour even vs using the actual datetime stamp [as shown above].

Any suggestions?

Getting a hourly forecast works fine as I'm not sending any parameters so it's not the JWT logic or anything like that...

Thanks,

this works for me. note that you need to update with your token: curl -v -H "Authorization: Bearer {YOUR_TOKEN_HERE}" "https://weatherkit.apple.com/api/v1/weather/en/35.0/-80.0?dataSets=forecastHourly&currentAsOf=2022-01-01T00:00:00Z&hourlyStart=2022-01-01T00:00:00Z&hourlyEnd=2022-01-07T00:00:00Z&timezone=America/New_York&countryCode=US"

the token can be created with python:

import jwt
import datetime

TEAM_ID = 'TTTTTTTTTT' #replace with your team_id from the apple developers site, keep in quotes
KEY_ID = 'KKKKKKKKKK'  #replace with key_id from the apple developers site
APP_ID = 'com.MyVeryOwnURL.WetterAPI' #invent this with your own domain in reverse
file_path = f'./AuthKey_{KEY_ID}.pem' # use full path to the key you download from Apple Developer Site. Note, I converted my .p8 file to .pem using `openssl pkcs8 -nocrypt -in AuthKey_KKKKKKKKKK.p8 -out AuthKey_KKKKKKKKKK.pem`

header = {
  "alg": "ES256",
  "kid": KEY_ID,
  "id": f"{TEAM_ID}.{APP_ID}"
}

current_time = datetime.datetime.utcnow()
expiration_time = current_time + datetime.timedelta(minutes=19)

payload = {
  "iss": TEAM_ID,
  "iat": int(current_time.timestamp()),
  "exp": int(expiration_time.timestamp()),
  "sub": APP_ID
}

with open(file_path, 'r') as file:
  private_key = file.read()


coordinates= '35.0,-80.0'
token = jwt.encode(payload, private_key, algorithm='ES256', headers=header)

# Create the curl command
curl_command = f'curl -v -H "Authorization: Bearer {token}" "https://weatherkit.apple.com/api/v1/weather/en/35.0/-80.0?dataSets=forecastHourly&currentAsOf=2022-01-01T00:00:00Z&hourlyStart=2022-01-01T00:00:00Z&hourlyEnd=2022-01-07T00:00:00Z&timezone=America/New_York&countryCode=US"

print(curl_command)

After that's done, run it in the terminal. it'll give you your the line you need to copy and explicitly paste to execute on the terminal.

good luck!
