Do you know which of these yellow...
... butterflies are found flying over the water offshore? We've been waaaay out on the Sea of Cortez and sometimes find lots of yellow butterflies
flying who knows where.

It would be hard to say which particular species you observed flying out in the Sea of Cortez without actually seeing the species or a specimen.
Offshore flight behavior is common and has been observed in many species of butterflies. Were your sightings unusual? Not at all.
There are several probable/possible causes of this phenomenon depending on whether they are migrating (in a preferred direction) or dispersing (in no
preferred direction). Most likely, high pressure weather systems often are ideal for generating thermals. These thermals always drift downwind, and
when a thermal that has formed over warm land drifts out over a cooler body of water, the supply of warm air feeding into the thermal is cut off and
the thermal dissipates. If the butterflies take longer to react to being drifted out to sea while riding thermals, the butterflies may be carried so
far off shore that they have to fly an hour or more to make it back. If the offshore wind picks up, they may never make it back. On the other hand, if
a sea breeze starts, butterflies that were struggling against a headwind may suddenly find themselves in a tailwind. They could then climb to higher
velocity winds above and be swept back to shore, once again flying high over the beach but in the opposite direction.
