Depends on whether it is worth $600 for you to fly non-stop. $1800+ seems awfully high, even for summer for a route like that.
That being said, word is that summer rates this year are just higher than in year's past, and that people need to expect to pay a premium for travel during summer months compared to years past, especially a busy time like August.
Good luck!
EDIT: Feel free to also use Google ITA Flight Matrix, or the more simpler Google Flights interface to compare flight prices to different months (both before and after) to get a better idea.
