Bioluminescence is best viewed during certain phases of the moon. The darker the night, the better viewing of the bioluminescence. We will not schedule bioluminescent tours during evenings where the moon is too bright to see bioluminescence. However, we will experience different levels of "acceptable" moonlight since there are only a few absolutely dark nights. We will still offer moonlight tours on those bright moon nights. An overcast night may result in seeing good bio even during days the moon is scheduled to be unacceptably bright. In season, bioluminescence is always visible in the shadows under the trees around the canal. You are responsible for choosing a night with a level of darkness that is acceptable to you.
 
Below are the moonphase calendars to help you schedule your trip:
