I'd guess so. We went 4? years ago, in late January. Every site off the southern side of the ring road had 4-5 tour buses full of tourists, plus assorted individual cars. It wasn't crowded to the point of annoyance, but it was close. What was annoying was poor behavior by many tourists - stepping inside the chains and touching water at Geysir, going into the "caldera" of Kerid Crater, and going near the water at Reynisfjara Beach. All despite many signs in many languages. And poor tour guides chasing the idiots back to safety. I'd guess if we went north, it would have been relatively quiet, but we only had 4 days, so based out of a flat in Reykjavik.
