How to Read a Tide Table
The ocean is constantly shifting in toward high tide or
out toward low tide. In Oregon there are two low and
two high tides every 25 hours. On a tide table, "L" and
"H" indicate the lowest and highest points predicted for
a specific day. Not all low or high tides are the same.
The height for each tide is listed with the time.
A tide table is read from left to right for a specific day.
It is easiest to imagine the table as four columns, each
indicating (by time) the next high or low tide.
Why use a tide table?
Knowing about the tides helps you get the most out of
a coastal visit.
Low tides are good for visiting tide pools, finding
sand dollars, and beach combing. Anything below
a 1.0 tide is good, but the best are the "negative"
tides (in bold, right). The lowest tide is not always
in the morning. Arrive at your destination at least
an hour before low tide, while the tide is still going
out. This will allow plenty of time to look around
before the tide changes.
High tides are good for fishing and crabbing.

Important Beach Safety
1. Never turn your back on the ocean.
Sneaker waves are very powerful, sometimes strong
enough to knock over an adult.
2. Avoid logs in the surf.
They may look stable, but the ocean can roll logs large
enough to crush you.
3. This is not a safe area for swimming
in the ocean. Be aware there is a strong undercurrent. Children should
be kept within arm’s reach and should go no deeper than
their knees.
4. Completely extinguish your campfires.
Embers can burn for days if left or covered.
5. Leave marine mammals alone.
Marine mammals can carry diseases transmittable to humans.

Here’s an example:
|
Monday, June 3, the tide will be its lowest at 3:33a.m. It will
reach 0.6 ft, after which it will start coming in. At 9:47a.m.,
the tide will reach its highest point, 5.4 ft, and then start
receding. The next low is a 1.6 foot tide at 3:18pm and the
next high tide is at 9:57p.m. It will be 7.5 ft.
