The article was posted at 3:27 on August 12th, and the incident happened at 2pm (but they didn't give the date). So I'm assuming that it either happened at 2pm on the 12th or possibly at 2pm on the 11th. So I've highlighted those two regions in yellow below.
I don't see anything particularly unusual at either of those times, so I don't see anything to justify blaming the conditions. As with most of these incidents, it's hard to tell what really happened because the people telling the story have their own agendas. I'm just happy to see that they didn't call it a "hang glider" as they have in the past when paragliders have crashed!!
