Missing pressure values in weather forecasts at night

I am consistently receiving missing pressure values when requesting forecasts.

I am using the following URL:

 https://weather.visualcrossing.com/VisualCrossingWebServices/rest/services/weatherdata/forecast?locations=37.762787,-122.385901&aggregateHours=1&unitGroup=metric&shortColumnNames=true&forecastDays=15&contentType=json&useEpochSeconds=true&key=MYKEY

Between the hours of 5:00PM and 1:00AM PST the API consistently returns forecasts that do not include the "sealevelpressure" key. I don't seem to have this problem outside of that time frame.

Is this expected behavior?

  Thank you for your question. This is not the expected behavior. Could you clarify if you see no pressure values in the response between 5pm and 1am or when you submit the request between those times? As of yet we've not been able to reproduce the problem.

  We also notice that you are using the /forecast API endpoint. If possible we recommend new implementations use our newer /timeline endpoint which combines both forecast and history into a single, consistent format. See https://www.visualcrossing.com/resources/documentation/weather-api/timeline-weather-api/ for more information.

  Regards

  Hello,

  Thanks for the reply. I am sending the request between 5pm and 1am roughly every 15 minutes. Each request is asking for a 15 day hourly forecast.

  In the meantime I will look into changing to the new endpoint.

  Thanks

  Hi Jonas

  our QA team double checked and could not see a similar behavior -

  can you send the query string and output to support@visualcrossing.com for further investigation please ?

  thanks
