The wind is creating a pressure difference that’s putting changing pressure on the water in the bowl.

Your toilet, and all plumbing, has a vent that goes outside so that you can flush and drain smoothly. If it’s very windy, air pressure from the wind blowing across that vent can affect the water in the toilet bowl.

Plumbing system has a vent, i.e. a pipe that connects to the outside air to allow air flow through the pipes as the water flows and displaces air.
As the wind blows, it also slightly disturbs the air in the vent pipes, which slightly disturbs the water.
