Water Temperature Measurements - 2020-09-20 - Portabello

The graph below shows a time series of temperature measurements (vertical axis) covering the 30 minute period of the swim (horizontal axis). The water temperature measurements covered a span of only about 0.2°C.

The temperature sensor reports temperatures in steps of 1/16°C. During this swim only four distinct temperatures were reported - 13.31, 13.38, 13.44 and 13.50°C.

The map below shows colour coded temperature measurements. A step of one colour corresponds to a temperature change of 0.1°C.

The same data can be viewed interactively on this map. Clicking on a circle brings up a pop-up which shows the temperature measurement at that point.
