Weather in Park City in August

Prime time. If you get to pick your dates, August is the one. Highs average 27 °C, lows 11.5 °C, and rain falls on 9 days — nothing in the month is working against you.

August ranks 3 of 12 in Park City. Only June scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 9 days, 0 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

Averages flatten a month, and this one hides a few things: 5 days top 30 °C — hot spells arrive, but they break; the day swings 15.5 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest August day reached 34.9 °C and the coldest night fell to 0.7 °C, and the wettest single day dropped 28 mm — roughly 90% of the month's rain in one day.

August is moderately variable: 1 mm in the driest year against 79 mm in the wettest, around an average of 31 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 1.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 44%.

How August sits in the year

Temperatures hold steady either side: 28.5 °C in July, 27 here, 21.9 in September. Nothing about the timing within the month matters much.

Daylight in August

13.8 hours of daylight, losing 1.2 hours across the month. That is between Park City's extremes of 15.1 and 9.3 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 39.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. At 2141 m, altitude is doing as much work here as latitude: thinner air means fierce sun by day and heat that leaves the moment it sets. Within August itself the daily swing is 15.5 °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.

August in Park City versus nearby

If Park City is one option among several, the nearby comparison is worth making. Salt Lake City is the weaker option in August — 5.2 °C warmer, 3 days less rain. Moab is the weaker option in August — 7.7 °C warmer, 1 day less rain.

So: August is effectively as good as it gets here — 4 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
