The average July temperature in my part of the world would be 20 C (70 F) with the average max being 26 C (80 F). Because of this, it is generally fine to live without air conditioning. However, we are having an unusually hot summer (minus last weekend which was the coldest July day since the records began in 1953).
For some perspective on how unusually hot this summer has been we have already had 4 days over 33 C (91F) when usually we only have 3 over the entire summer and 1 by this time of year. We have also had 11 days over 31 C (88F) when normally we only have 8 during the entire summer and only 3 by now.
Because we don't have air conditioning, today I am thankful for the fans we have. They help keep the air moving and the one beside my bed keeps me feeling cool while I sleep.
