A few others have mentioned regulations. Luckily the country where I am taking the drone to hasn’t got any.
But the location is right by the sea. Strong gusts and sudden change in wind directions sank many a sailing ship there in centuries past. So the suggestion of looking at a drone with some level of automation makes perfect sense. Especially since I want to use the drone to film the shoreline from the direction of the sea.
Well... here's the thing where strong gusts of wind are:
The big, "stupid" drones like the DJI Phantom 3 and Dji Phantom 4 will do better than the smarter, smaller drones like the mini 3 pro and such.
I mean, one should NEVER fly a drone when it is too windy. But my big, loud and obnoxious phantom 3 and phantom 4 drones do a lot better when it is windy than my mini 3 pro does.
For safety's sake, if you drone will be over the sea and you want to look back at the shoreline, you would ideally want to fly when the winds are blowing toward the shore (as opposed to when the winds are blowing out to sea). That way, when you are low on battery power after filming for a while, the wind will be blowing you in the right direction (toward the shore, where I assume you will be launching). Of course, waiting for the wind to blow toward the shore might not be practical.
Also, sometimes automation can be BAD when flying in strong winds. Most drones WON'T use full power when flying in their automated modes, and you have to switch in to Sport mode to use the full power of the motors. I've heard horror stories of people who were flying on a windy day and then used the automatic "Return To Home" feature only to see their drone be blown off over the horizon because the winds were too strong.
getting smooth footage in gusty wind will always be a significant challenge.
