I used Adobe Illustrator to make the chart.

What program did you use do design that pretty chart?

Trestles and South Texas have broad, sandy beaches but if this data were from were eroded beaches in New Jersey I would think tide stand was negatively correlated with beach area. Not much beach left for sunbathing at high tide! LOL.

Surfrider also had a big role in saving Trestles from getting paved over by a superfluous toll road. Very cool research for preventing future destructive development.

This is a generalized graph of surfing and beach going that is loosely based on my findings at Trestles as compared to beach going from the Southern California Beach Valuation Study (Hanemann, Pendleton, et al 2001) as well as anecdotal information from surfers.

It does look like a tide chart!

The tides shift about 50 minutes later each day so over a season or a year you’ll find that during some weeks and at some surf spots the tide will be a factor in the timing of surfing or in site choice for surfers. It is also important to note that some surfing spots are more tide sensitive than others. Trestles happens to be a place that can be surfed at almost any tide.

So the influence of the tide on this graph would depend on the surf site and what time period you were describing.

I’d like to see a tide chart underlayed on that graph…
