Puget Sound Clamming Calendar 2012
The following chart shows the optimal clamming days based on a rather simple algorithm. The algorithm uses the tide height (negative is better of course), the proximity to noon and the day of the week (weekends are better, holidays are not yet factored into the equation).
Note: For recreational digging purposes only. Not to be used for navigation or situations where people or property may be at risk. Accuracy cannot be guaranteed.
