Osoyoos Weather
Best In Canada

Osoyoos weather is what people usually bring up when talking about Okanagan weather in general.

Now the weather, in my opinion, is perfect anywhere you go in the Okanagan Valley.

But Osoyoos is the place to go for the sun seekers looking for real summertime hot temperatures.

I believe it has the best BC weather and probably the best weather in Canada.

Osoyoos usually doubles its population of just over 5000 people during the summer months.

The ideal weather and outdoor recreational options available because of this are major factors in the influx of people to this city.

It is a major travel destination for many visitors to the Okanagan and is a place you may want to book early as tourists flock here.

Osoyoos Climate

Osoyoos is known as Canada's only desert. The town sits at the very northern edge of the Sonoran Desert which extends all the way down into Mexico.

The area is often referred to as the Osoyoos Arid Biotic Zone. You get a sense of being in a desert as the town is surrounded by cactus, rolling dunes and tumbleweeds.

It is quite the sight!

The unique location of Osoyoos at the base of the Cascade Mountains means it is in a rain shadow. This causes there to be very little precipitation each year.

Osoyoos weather is also a factor in Osoyoos having one of the longest growing seasons in Canada.

And one of the earliest growing seasons too.

From July to September each year choose fruit like apricots, cherries, peaches, pears and plums from the numerous fruit stands throughout the area.

Only one word comes to mind.


The hot weather contributes to Osoyoos Lake being the warmest freshwater lake in Canada.

The lake temperature in the summer average 24°C (75°F). Just imagine swimming or floating in these waters.

Many people do and that is another reason the crowds flock here each and every year.

A Few Osoyoos Weather Facts

  • Osoyoos enjoys the warmest summer daytime average temperatures in Canada at 27.9°C (82.2°F)
  • During July and August average temperatures are around 30°C (86°F) with lows overnight around a very pleasant 14°C (57°F).
  • September and October are usually quite warm and an "Indian Summer" is quite the norm for here.
  • Winters are short and mild with average lows being around -5°C (24°F) in January. Most daytime temperatures hover around the freezing mark of 0°C (32°F).
  • Spring arrives earlier than other parts of the Okanagan and you can start getting nice Osoyoos weather by April.
  • Temperatures typically reach the upper 30's°C (95°-104°F) in the summer months.
  • The town of Oliver, which is just 21 km (13 mi) north of Osoyoos, hit a daytime high temperature of 43.9°C (111°F) on July 16, 1941.
  • That same day Lytton and Lillooet, both communities in the British Columbia interior, recorded the highest temperatures ever recorded in the Province at 44.4°C (111.9°F). Whew. Now that is scorching hot!
  • Now Osoyoos temperature records only go as far back as 1990. So there is a very strong chance that Osoyoos either met or surpassed these temperatures as it tends to get warmer than Oliver.
  • There is over 2000 hours of sunshine in this area each year.
  • There is only about 250 mm (10 in ) of rain and 50 mm (2 in) of snow that fall here annually.

As you can gather from this information Osoyoos weather is pretty well ideal all year long.

The city attracts a lot of retirees wanting to get away from it all and enjoy a climate that is so much nicer than the rest of Canada experiences, especially in the winter months.

I have camped several times in the Osoyoos area and it really is a fantastic place for anyone wanting a holiday get away.

Just make sure you bring lots of sunscreen and your favourite beach wear and you are ready to experience a desert oasis.
