Beach Weather Stations - Automated Sensors - 2015 - Humidity
data.cityofchicago.org | Last Updated 23 Sep 2016The Chicago Park District maintains weather sensors at beaches along Chicago's Lake Michigan lakefront. These sensors generally capture the indicated measurements hourly while the sensors are in operation during the summer. During other seasons and at some other times, information from the sensors may not be available. See https://data.cityofchicago.org/id/qmqz-2xku for a dataset with similar measurements on the lake water, itself.
This dataset has the following 18 columns:
