Weather in Spokane in July

Prime time. If you get to pick your dates, July is the one. Highs average 29.9 °C, lows 14.7 °C, and rain falls on 3 days — nothing in the month is working against you.

July ranks 5 of 12 in Spokane: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain falls on only 3 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29.9 °C days and 14.7 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 16 days top 30 °C — hot spells arrive, but they break; the day swings 15.3 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest July day reached 38.5 °C and the coldest night fell to 6.7 °C.

July is moderately variable: 1 mm in the driest year against 35 mm in the wettest, around an average of 11 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 6.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 50%.

How July sits in the year

Temperatures hold steady either side: 23.8 °C in June, 29.9 here, 29.3 in August. Nothing about the timing within the month matters much. Rain has already shifted: 5 days fewer than June had.

Daylight in July

July is at or near the longest days of Spokane's year: 15.6 hours of daylight, losing 0.9 hours across the 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. Within July itself the daily swing is 15.3 °C, so mornings and afternoons need different clothes.

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.

July in Spokane versus nearby

If Spokane is one option among several, the nearby comparison is worth making. Tri-Cities is the weaker option in July — 4.4 °C warmer, 2 days less rain. Kelowna is close enough to be a coin toss — within a degree on temperature, 3 days more rain.

So: July works, with September the better month by 12 points if the dates can move. If they cannot, nothing here should stop you booking.
