Big wave surfer Garrett McNamara likely set a new world record when he surfed a 100-foot wave in Portugal this week.
McNamara set the current record in 2011 when he rode a 78-foot wave at the same spot in Nazaré, Portugal. Here's some more mind-melting footage from his day at the beach.
To put a 100-foot tall wave into perspective, here are a few things that measure 100-feet:
Most 10-story buildings.
1 full length NBA court (with six feet to spare).
2 standard IMAX screens.
100 1-foot waves.
A stack of five average-size giraffes.
A stack of 14.2 Andrew Bynums.
