Can I walk along the ocean from Cannon Beach, Oregon, to Hug Point or Adair Point?

Supplemental info to Michael Seifert's good answer

how to determine when the tide is low enough?

1. Call the recreation park and ask at what water level it's safe/dry to walk.
2. Use the tide table to determine which times are safe
3. Plan your hike so that you are at hug point at a safe time. Keep track of time.

I can find the tide information, but I can't "read" it so to speak.

You can find tide tables online. See for example https://tides.willyweather.com/or/tillamook-county/hug-point.html

The curve shows the water level as a function of time relative to the "average low tide". There are 2 high tides and two low tides every day and they are about 6 hours apart. The times do change a little every day, so you need to look them up. The difference between high and low tide can be more than 6 feet which is the difference between dry feet and potential drowning so it's important to pay attention.

Hug Point appears to have a somewhat unusual tide pattern, at least at the moment: the two low tides each day have very different water levels and the morning one is not very low.

Example: if the park tells you: it's safe to walk there when the water level is 2 feet or less then on Sunday Dec 5, you would have to be at Hug Point between 7pm and 12:30am the next morning. That's the only times on Sunday where the water is 2ft or below.
