I've read in the weather pages that July and August is best to be avoided when going to NYC because of the heat and humidity. It ranges from 67F to 82F (19C to 27C). This doesn't appear to be very hot given we have many days in Sydney where its close to 104F (40C) during the Summer. We are quite humid as well. But the pages does indicate its quite uncomfortable during that time.
I was wondering whether someone from Sydney can give some advice on weather end of July early August in NYC as a comparison so I can put some perspective on what to expect and whether it will be tolerable for me.
I plan to do a lot of walking so getting quite nervous about whether to go or not.
