Calculate a weekly mean

This example uses NOAA water sample data.

This example calculates a temperature weekly mean and stores it in a separate bucket.

The sample query performs the following operations:

  • Uses filter() to select records with the average_temperature measurement.
  • Uses range() to define the start time.
  • Uses aggregateWindow() to group records by week and compute the mean.
  • Sends the weekly mean to a new bucket (weekly_means).
option task = {
  name: "weekly-means",
  every: 1w,

from(bucket: "noaa")
  |> filter(fn: (r) => r._measurement == "average_temperature")
  |> range(start: 2019-09-01T11:24:00Z)
  |> aggregateWindow(every:  1w, fn: mean)
  |> to(bucket: "weekly_means")

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
