With all the rain Southern California received during the 2025-2026 rainy season, optimism is in the air that the region will once again welcome a super bloom, a desert botanical event during which wildflowers bloom in large areas at the same time.
The good news is that Southern California has had all the makings for a super bloom in the deserts so far. But the bad news is it takes more than rain to create a prime condition for a super bloom.
According to Todd Michaels, a research professor at Salk Institute for Biological Studies, the temperature and wind will need to cooperate.
“Right now, it’s looking like in Anza-Borrego. Maybe not. Maybe we’ve had too much heat already,” Michaels said, explaining the recipe for a super bloom has to be perfected before the rare natural event can happen.
He said Death Valley in California’s Mojave Desert may be more likely to see the large-scale blossom, a decade after its 2016 super bloom.
And if a super bloom were to happen in Southern California, it would happen soon: According to Michaels, late February to late March is the window for a super bloom. For high-elevation areas, it could happen between late March and late April.
The last notable super bloom happened in Lake Elsinore in 2018 as an overwhelming number of visitors sought out the wildfire bloom. After being swamped with tens of thousands of visitors, the city of Lake Elsinore eventually had to enforce parking restrictions and operate shuttles to accommodate the influx of pelople.
