Go to Thailand. I went there for Honeymoon during off season and it was my best VACATION ever. Or you can come to Czech republic. Great sandstone(trad and sport) climbing and its cheap to stay. June, July August are the best moth here. https://picasaweb.google.com/118086742536778898618/AdrNaKole
Thanks everybody for the suggestions. I'm liking the idea of being right by da beach... I just an artcile in Climbing about Puerto Rico. I imagine it would be pretty hot and hummid there in July though...?
I was going to suggest Cayman Brac, www.climbcaymanbrac.com, but in July? No. And neither Puerto Rico, unless you really like to sweat. Maybe delay the honeymoon? A tropical island is SO much better in the winter.
I don't know why people are telling you to go to Rumney, The Red, The New or St George....those are probably the worst places you would want to go for climbing in July, you'll be miserable. Head west (the further north, the better) or to Europe. That's it.
Over half of the places mentioned will be terrible in July. I don't need to tell you which ones. Unfortunately, many of the best sport climbing areas are terrible in July. Even if you travel south of the equator, it's the middle of winter.
I would recommend looking into Tenerife in the Canary Islands. It is known for its amazing weather year round. The average high for July is 77, the average low is 64, and it won't rain a drop. Plenty of climbing at your grade, and plenty of things to do. You can ride horses on beautiful beaches and hike to the highest point in Spain. It's also relatively cheap, although July is tourist season.
