They still closed for part of the time early in COVID, but quickly switched to partial in-person with significant outdoor time. I think it was effective, surely better educationally and socially than my younger’s elementary school that stayed closed for a far longer time.
Being in CA, that's easy year round due to milder weather.
That said, the effort was nothing close to outdoors all the time, which has significant challenges.
1. Divide into "capsules" where people could learn indoors but with half of the cohort - spread apart, windows open, masked, etc.
2. Learn outside with forms of this.
Youth groups, scouts, synagogues, etc all did the latter. I spent the better part of a year praying in a parking lot or a park with others. Entire communities were doing shared meals - just spread apart. The park across the street from my place had a lot of picnicking going on.
As an example, the local Planetarium rejigged to do outdoor events. They were so popular that the planetarium continues to do ~40% of each season's lineup outside.
When it rains, they wear galoshes and get suited up.
Forest schools tend to have a "learning through play" philosophy, at least the ones I'm aware of.

I suspect they do well at socializing kids, and letting them figure things out for themselves. Definitely not doing some version of teaching to the test.
Other advantage: it stayed open during COVID.
Disadvantage: The smoke season in CA is a problem.
As far as the hotter areas in the South, there's probably some solution for that too.
You do need some sort of shielding from the sky, heatstroke is a thing, so's an absolute drenchpour that lasts about twenty minutes, usually in the afternoon.
I just remember walking my dog there daily and seeing kids.
On the topic there are a category of preschools in Sweden called "Ur och skur" which have most education outdoors.
Back in the 90s I know some primary schools in Sweden also had education outside, but I think that have changed with schools becoming more competitive lately.
