This big-brimmed hat was shown on the cover of Delineator, August 1930. Illustrated by Dynevor Rhys. It may be based on Butterick pattern 3816, shown later in this post.
The transition from 1920s to 1930s was more gradual in hats than in dresses. The cloche was still around, but tiny hats and huge hats were also featured.
Five different hat styles appeared on the same page in Delineator, August 1930.
Above, Hat B is a familiar cloche, Hat C clings very tightly to the head, Hats A and D have wide brims, and Hat E is cut away in front, with most of the brim at sides and back.
You would expect these wide brims in summer; August 1930.
By summer of 1930, the natural waist is everywhere.

I find 1930 hats with a pleated brim very attractive:
Left, a medium-width pleated brim. August 1930.
Another pleated brim from August 1930.
Wide-brimmed hats were especially seen with afternoon dresses:
A long, formal afternoon dress is topped with a very wide brim. August 1930. You can imagine this woman is a guest at a wedding.

However, wide brims were also worn for sun protection with casual dresses and even pajamas:

Butterick offered this versatile hat pattern in 1931.

The one second from left doesn’t have a brim, just a “binding.”

The version at lower left resembles the hat featured on the August 1930 Delineator cover.
Very similar to Butterick 3816, but with added trim inside and outside the hat.

It shouldn’t be too difficult to copy those flowers and add them to a purchased straw hat!
A big hat was still appropriate for summer in 1933:
