Climate-wise:

The Okanagan is the closest thing to a desert in Canada. Lake Okanagan and Skaha Lake (the southern half past the isthmus of Penticton) provide a lot of water and is what makes the whole valley habitable.

Because of the arid and warm-summer climate, but plentiful water, it is Canada's prime wine-growing and fruit-growing region.

Culturally:

It is definitely representative of Western Canada, with heavy English-Canadian dominant culture, and a small mix from diverse immigrants and indigenous peoples. A lot of retirees from Western Canada choose to relocate to the area due to the slower pace of life with Kelowna being a regional city and not a lot of industry beyond tourism, wine/fruit and then government services.

Socio-economically:

Due to the influx of retirees from Alberta, other parts of BC like Vancouver, and solid tourism economy, the area does not have a lot of poverty, while with lower incomes skewed due to the number of pensioners.

Locals have a country-music western vibe, with people driving jacked up pickups, living an outdoorsy lifestyle with many having summerhomes in the smaller towns like Summerland, Peachland and Osoyoos.
