context_page_description: Penticton is a city in the Okanagan Valley of the Southern Interior of British Columbia, Canada, situated between Okanagan and Skaha lakes. In the 2016 Canadian Census, its population was 33,761, while its census agglomeration population was 43,432.
context_section_description: Penticton has a cold semi-arid climate (Köppen climate classification BSk) bordering on an oceanic climate (Köppen climate classification Cfb) and humid continental climate (Dfb bordering on Dfa). Penticton has low precipitation, hot summer days with cool nights, and moderately cool, mostly cloudy winters. With 346.0 mm (13.62 in) of annual precipitation, Penticton is the fourth driest city in Canada. It averages 58.7 cm (23.1 in) of snowfall per year. Penticton has the mildest winter of any non-coastal city in Canada.
  The high daytime temperatures throughout the summer means that Penticton has on average the second most number of days in a year over 30 °C (86 °F) (after Kamloops) and the city has the lowest amount of fog in Canada. Penticton experiences 1,923 sunshine hours annually, lower than one might expect in a dry climate. This is the result of temperature inversions during the winter that leave a layer of cloud cover at the top of the valley where warm moist air collides with the cooler dry air that fills the valley. During December and January, Penticton is one of the cloudiest places in Canada. By contrast, the summer months are some of the most cloud-free in Canada. Overall the sun shines for 39 percent of daylight hours, varying between a low of 13 percent in December and January to 62.6 percent in August.
  Mean relative humidity hovers between 63–77 percent in the morning throughout the year, but afternoon mean relative humidity is more uneven, ranging from 36 percent in July to 69 percent in January and December. The local and upcoming weather of Penticton is observed at the Penticton Regional Airport by Environment and Climate Change Canada. It typically experiences four distinct seasons annually, having hot summers, relatively mild winters, and little snow, according to the British Columbia government based on statistics from Environment Canada. Despite having a mild winter, Penticton often sees moderate stretches of below freezing weather, typically confined to December and January.
