First image shows weather details for 5.2.2009. Max. temperature was 29,2 C and min. temperature was 22,2. Second image shows area, which is located in the highest temperature area on the first image in Sydney CBD. The third image shows Bondi Beach area (not visible on the first image), where the temperature at the same time was probably much lower. These measurements were taken 8 years ago and I assume that nowadays, the difference between highest and lowest temperature is even higher than it used to be. 3.

The City of Sydney is collecting information to see how shade trees and pavement colour affect urban temperatures. Monitoring systems have been installed in Chippendale and Redfern.  The poles contain a temperature and humidity meter, and one has a pyranometer which measures the strength of the sun. Each also has a unit that sends the information to a server where it can be viewed online, and a small solar panel to power it all.
