Waimea Bay: Extreme Activities on the Oahu North Shore!

Waimea Bay in Summer

61-031 Kamehameha Hwy,
Haleiwa, HI 96712

With its broad, white sandy shore and crystal-clear aquamarine water, Waimea Bay Hawaii is easily one of the most idyllic beaches on earth!  Ever since the first westerners landed on Oahu at Waimea in 1779, the unique beauty of this legendary Hawaii attraction never ceases to amaze.

Furthermore, this world-famous North Shore Oahu beach also packs a world-class one-two punch when it comes to extreme activities – making it a “must-see” for your Hawaii adventure vacation!  But before you can choose the activities that appeal most to you, you’ll first need to determine when you’re going to be here.

At Waimea Bay, the seasonal water conditions have the final word on which activities are right for you.  That’s because from summer to winter, this epic Oahu beach undergoes a seasonal transformation comparable to Dr. Jekyll and Mr. Hyde…

Waimea Bay in summer means cliff jumping and water activities:

Waimea Bay in Summer

In the summertime (approximately April to September), when there is generally no surf anywhere on the north shore, Waimea Bay is a fantastic place for your family’s Hawaii beach vacation.  The sand seems to just stretch forever (continuing into the shallows for ideal water play with no reef shoes required)!   The calm conditions are not only perfect for young children to safely splash around – they’re also excellent for snorkeling and stand-up paddle boarding.  The bay is well-sheltered from currents and other open water hazards.  Basically, it’s practically perfect in every way – in the summer.

The Jumping Rock at Waimea Bay

And then there’s the rock – a big black monolith sticking up to approximately seven meters out of the sand and water on the left edge of the bay (facing the water from shore).  I promised you some Hawaii extreme activities, and most of those revolve around the rock.  Your introduction to cliff jumping/diving should probably begin here.  This is the Goldilocks cliff jump – not too high and not too low.  It’s approximately twice as high, and several times more thrilling, than the rock at Sharks Cove.  But it’s just a little more than half as high, and significantly less scary, than the rock at Kapena Falls.  It’s just high enough to seem a little intimidating without really threatening any serious danger.

Splashdown After Jumping Off the Rock at Waimea Bay

The rock at Waimea Bay is easy to climb from the end that appears to have run aground on the beach; and its smooth surface is mercifully easy on your bare feet.  Better still, it’s even easier to get back down again – if you have the nerve.  Anywhere past the approximate middle of the rock is generally a safe spot to catch the express elevator down to the water!

The highest point is basically right in the middle of the rock.  If you don’t feel comfortable starting there, first jump from a lower spot out toward the end.  You can jump from either side of the rock; but be aware that the back side (facing the edge of the bay) has a rockier bottom, whereas the front side (facing the bay) has an almost entirely sandy bottom.

Underwater Tunnel Through the Rock at Waimea Bay

Another exciting feature of the rock at Waimea Bay is that there’s an underwater tunnel that allows you to swim right through it!  If you’re not quite ready to swim the underwater lava tunnels at Sharks Cove, this might be more your speed.  Approximately two-thirds of the way out into the water – almost exactly at the spot where most people jump – and a little less than one meter underwater, this little cave is about the same size and length of a large sofa.

Once you know where this tunnel is located, you can trick your friends on the beach by jumping down in front of the cave entrance and then, without re-surfacing, swim through it to the other side.  Just make sure nobody’s jumping off the back side of the rock where you’ll be exiting the tunnel.  You really don’t want somebody to land on you because they don’t know you’re there.

Waimea Bay in winter means world-class big surf watching:

Waimea Bay in Winter

If you go to Waimea Bay when the winter surf is getting big (approximately October to March), you’re in for a much different extreme adventure!  Just compare the pictures at left and above.  It’s not uncommon to have waves crashing across the top of the jumping rock and/or a five-meter shore break (measuring by wave face) crashing into the sand across the entire width of the bay!  Trust me when I say that winter at Waimea Bay is for experts only!

No longer should you think about letting your kids play in the water.  No longer should you plan on jumping off or swimming through the rock.  Just stay the heck back from the water and watch the masters at work!

Big Surf at Waimea Bay

The winter surf at Waimea can get as big as about 15 meters (measuring by wave face)!  And there are a lot of surfers skilled enough to ride these monsters!  You, however, are not such a master.  Don’t plan on trying out your new boogie board in these conditions.  Just by watching, you can get all the excitement of man vs. Mother Nature without the tons of seawater pushing you down toward the seafloor.  And you’ll be in good company...

Big Surf Watchers at Waimea Bay

One thing’s for sure: when the waves get big, there are a lot more spectators than there are surfers.  They pack the beach and line the road on both sides of the bay for hours just to see the greatest surfing spectacle on earth!

Unfortunately, when the surf gets big, the normally inadequate parking gets downright horrible!  Unless you beat the crowds to the bay at the crack of dawn, you’re unlikely to find any available parking in the lot.  That’s when you’ll discover that there really isn’t any parking elsewhere.  There’s no parking along the roadside around (or anywhere near) the bay; but people will do it anyway, which will pinch the traffic and cause somewhat major delays.  Meanwhile, the police will patrol the whole area every few minutes and ticket or chase-off the worst offenders.  Many more people will park at the church that overlooks Waimea Bay.  That too is not allowed; and sometimes the church staff is vigilant about running-off non-parishioners.

It’s during these times that the Waimea Valley (across the street from the entrance to the beach) will put out a sign offering pay-for-parking.  All I can say is: get there early or be prepared to walk/pay.

If you’re here in December through February and the surf gets truly huge (face heights greater than 10 meters), you might even get to watch the Quicksilver in Memory of Eddie Aikau Big Wave Invitational Surf Contest.  This is the biggest of the big for the best of the best!  Since its inception, this contest has only been held one of every three years due to insufficient wave height on the other years.

Tips for fun and safe Hawaii adventures at Waimea Bay:

Check Water Depth Before Jumping Off the Rock at Waimea Bay
  • Make sure you check the water’s depth (or watch others checking the depth for you) before you jump off the rock at Waimea Bay.  During my most recent trip out there, the tide was so unusually low that I couldn’t even jump from the high point on the rock.  The water was only two meters deep where it would normally be closer to three meters.  Of course you’ll unavoidably check it again as soon as you splash down, but that’s generally too late.  Check first and then jump – not the other way around. 
Rescue at Waimea Bay
  • There are bathrooms, showers, and a well-maintained picnic area at Waimea Bay, but there are no other conveniences (concessions, etc).
  • Parking is often inadequate even on the less-crowded days.  Arrive early for your best shot at availability.
  • There are lifeguards on duty throughout most daylight hours every day.  They’ve got a huge job watching this bay (especially when the surf is big).  Don’t make it any harder for them by failing to properly assess your abilities.
Hazard Warnings at Waimea Bay
  • If access to the water is blocked by a yellow warning tape and bright orange flags, heed the warning.  That tape and is there for your protection; and it’s half-way up the beach because that’s the minimum safe distance to keep you from getting pummeled and swept out to sea by the massive shore breaks.
  • Even on a calm day, there can still be a bit of a current in the water.  Pay attention to your surroundings so that you don’t just drift with the current out into the open ocean.
Rock Climbing at Waimea Bay
  • Regardless of the season, one adventure activity can be enjoyed year-round: rock climbing.  In addition to the jumping rock at Waimea Bay, you’ll also find what looks to be a fairly-challenging but short (approximately eight meters) climbing rock in the wall of the cliff surrounding the bay.  This rock is located straight back across the sand from the jumping rock.
  • There is very little shade on the beach at Waimea Bay.  Meanwhile, there’s adequate shade in the picnic area of the park, but you can’t watch your kids playing in the sand or water from there.  Basically, you should give yourself a good covering of sunscreen and wear protective clothes.  You might even want to bring a golf umbrella or small canopy.
Broken Surfboard from Big Waves at Waimea Bay

Disclaimer: Stupidity and carelessness can kill you.  Massive walls of water stretching across the entire bay can also do the trick.  Never turn your back to the waves.  Heed posted warning signs.  Watch your kids like a hawk.  Use your brain and take responsibility for your own safety.  Know the limits of your ability and stay within them.  I’m not recommending these activities.  I’m simply giving you information.  The decision to do these activities is your own.  Don’t give in to peer-pressure if these activities are beyond your ability.  Just volunteer to take the pictures, and live to happily enjoy another Hawaii vacation day!
