Still a little too early to do a proper guess, so much variables, especially for outdoor. I used to ask people the same but after a couple of harvests i found you can never guess a proper estimate for yield when its a few weeks from harvest. Wait until the last week or so before harvest and judge for yourself how dense the buds since pics can't show us lol. Strains/phenos/weather/knowledge/medium/nutes all play a roll on how dense your buds will be. If you have what looks like a lot of weed but its very fluffy it won't weigh much.
