The temperatures tested equal to 77 -104 degrees farenheit and the percent difference in the coldest and hottest day (27 degree difference) was 26.4% so the same can be concluded if Southern California ocean temperatures go from 50-77 degrees since the difference is still 27 degrees the viscosity difference is still 26.4%.

Therefore the hypothesis is barely true (by 1.4%) humans can feel a noticible difference in the oceans waves water thickness between the hotest and coldest days of the year in Southern Californa.
