Kelowna weather in May

Forum posters describe March in Kelowna as genuinely variable, capable of cold, wet and gray conditions or a brief bracing, sunny stretch, with one visitor recalling snow still on the ground in late March. Posters are consistent that March isn't peak tourist season, meaning fewer crowds but also more limited hours or closures at some attractions. Posters generally describe late March as pretty mild by Canadian winter standards and clearly warming compared to deep winter, though still well short of t-shirt weather. Posters flag that early March can bring real snow on the highways connecting Vancouver and Kelowna, especially at higher elevations along the route. Posters generally rate March as a genuinely mixed-bag month, workable for a visit but not a month to expect settled spring weather.

September is the month Okanagan regulars name as the best of the year: near 24°C by day against a July and August that can reach 35 at the south end of the valley, with the crowds gone and the heat dry rather than humid. Nights cool to about 14. It is also harvest, which is the point if wineries are the reason for coming — though the forum's own advice is that the density and variety are greater south of Kelowna, from Summerland through Penticton and the Naramata Bench down to Oliver.
