I've just spent a few days in Kelowna, B.C. Kelowna is a pretty city that sits in the Okanogan Valley and wine country. The city is long and narrow, bordering Okanogan Lake.
It has a population of 107,000, which seems to swell during the summer and for rush hour traffic.
Full of lush trees, the city was very warm the first week of September, when I was there. Most days were close to 30 degrees celcius. Luckily the city also cooled down each evening. After a summer of nearby forest fires, the air was surprisingly clear and fresh. A few evening rains certainly helped!
