Do I need a waterproof housing for surfing with a GoPro?

No. Modern GoPro cameras are waterproof to 33 feet without any housing, which is more than sufficient for surfing. However, a housing adds impact protection against board dings and wipeouts, and extends the depth rating if you also dive. For pure surfing, the naked camera with a good mount is perfectly fine.

What resolution should I film my surf sessions in?

4K at 60fps is the sweet spot for surf filming. It provides excellent detail for viewing on TVs and monitors while keeping file sizes manageable. Higher resolutions like 5.3K are useful if you plan to crop or reframe in post. For slow-motion wipeout replays, 1080p at 240fps creates stunning results.
