Summer of Data, Part 2


Summer of Data, Part 2

Continuing with my Tableau blog series called the Summer of Data, I’m using Tableau to explore different and interesting data sets. All the visualizations are published to Tableau’s robust public platform, Tableau Public.


As we’re heading into the heart of this summer’s holiday season, I thought it would be fitting to take a look at the weather. For this iteration of Summer of Data, I’ve taken advantage of the open data at Statistics Finland (Tilastokeskus), and pulled temperature readings from the beginning of the 1800’s. Statistics Finland collects data for various socio-economic categories, and all of it is freely available to download and analyze.


In the data viz below, I’ve extrapolated the different seasons from the data as well as used Tableau’s bins feature to create year ranges for my analysis, as the data has been collected from the beginning of the 1800s. For the forecast, I’ve also used another built-in analytics tool in Tableau — Forecast. The model built into Tableau uses exponential smoothing to calculate the forecast. For my forecast, I’ve used the historical data in my dataset to predict what the temperature will be for each season in 2066.
