Weather in Spokane in June
United States · 20-year averages, June
Prime time. June is about as good as Spokane gets. Highs average 23.8 °C, lows 10.6 °C, and rain falls on 8 days — nothing in the month is working against you.
June ranks 2 of 12 in Spokane. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain on 8 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest June day reached 40 °C and the coldest night fell to 2.7 °C.
June is moderately variable: 10 mm in the driest year against 97 mm in the wettest, around an average of 40 mm. Roughly two Junes in three land near that average, and the third does something else entirely.
Wind is light at 7.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 60%.
How June sits in the year
The month is on the way up: 3.8 °C warmer than May, and July adds another 6.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain is the thing that moves: July brings 5 days less of it, so pushing the dates later buys drier weather.
Daylight in June
June is at or near the longest days of Spokane's year: 16 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
With no coast nearby, the year swings a fair way — 34.9 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
June in Spokane versus nearby
If Spokane is one option among several, the nearby comparison is worth making. Tri-Cities is close enough to be a coin toss — 4.7 °C warmer, 3 days less rain. Kelowna is close enough to be a coin toss — within a degree on temperature, 5 days more rain.
So: June works, with September the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
