Sydney is having an incredibly pleasant summer, hitting peaks of around 29 degrees Celsius daily. It is not even particularly humid. Still, after so many Tokyo summers of burning, dripping heat, I think my tolerance levels are forever lowered. Give me a nice, temperate 23 degrees Celsius any day --- please.
OK, OK, I am spoiled. Childhood summers were spent in Buderim, QLD, with the best beaches in the world at our feet, literally. I have yet to meet a beach that matched up to them, anywhere in the world.
Maybe, it is just that summer in the city, well, sucks. No matter where you are or how close the beaches are.
