NOTE: You can encounter jellyfish at any time, these are just the most likely days you will see them at a south shore beach on Oahu. Check with lifeguards and posted signs before going into the water. These estimated dates are for box jellies only and other hazards such as Portuguese man-of-war can appear at any time as well.
