With a stationery low pressure trough, close to the B.C coast, the first two weeks of June were predominantly wet and cool.

On June 19th, a transient ridge of high pressure produced welcome sunny skies and peaked the temperature for the month to 28.0 ⁰C (28% relative humidity). However, this was the lowest June maximum temperature in 8 years. After the low temperature for the month of 7.2 ⁰C on June 1st, on June 20th there was a high record minimum of 16.2 ⁰C (5.9 ⁰C above normal). The previous high minimum was 15.8 C in 2018.

With reoccurring upper level low pressure troughs, generally showery conditions prevailed to months end.

Because of the mostly cloudy conditions, above normal overnight minimum temperatures contributed to mean temperatures for the month being 0.49 ⁰C above normal. It was the 8th consecutive June with above normal mean temperatures, a warming trend never previously observed since Chilliwack records commenced in 1881.

Extreme UV levels were reported on 4 days, peaking at a record 12 rating on June 22nd.
