Are there still wildflowers to see?

No, last week, I was there, almost all flowers were gone. I do not think raining these days would be helpful.

We were there last weekend & there were some patches of wild flowers, but we missed the peak of the super bloom. However, you should consider visiting the "slots" of Anza Borrego.

There are some at higher elevations but for the most part they are gone because of the heat
