summer daytime temperatures in the southwestern interior are the hottest in canada. during july and august, the average daily maximum temperature around osoyoos and spences bridge is over 29 °c (84.2 °f), though lillooet and lytton erroneously claim to be hotter and vie for the title of "canada's hot spot". this is because their summertime temperature extremes tend to be hotter than osoyoos and spences bridge (despite a slightly cooler average temperature). this heat combined with little precipitation means that arid animals and vegetation thrive. although winter temperatures are much colder than coastal british columbia, many interior areas have warmer winters than most of the other provinces in canada. southern interior valleys, including the okanagan valley, are spared the incessant precipitation found on the coast, but they receive some of the lowest amounts of bright sunshine in canada
