Weather in Zaragoza in August

Shoulder season. August is shoulder season in Zaragoza — cheaper, quieter, and a genuine gamble. Highs average 33.8 °C, lows 18.7 °C, and rain falls on 4 days — nothing in the month is working against you.

August ranks 11 of 12 — near the bottom of Zaragoza's year. October is the month that works, and the swing between the two is 39 points, which is a different holiday rather than a slightly better one.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 33.8 °C days and 18.7 °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: 13 days clear 35 °C, so a serious heatwave is normal rather than notable; the day swings 15.2 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest August day reached 43.1 °C and the coldest night fell to 11.7 °C.

August is moderately variable: 4 mm in the driest year against 52 mm in the wettest, around an average of 18 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 10.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 49%.

How August sits in the year

Temperatures hold steady either side: 34.2 °C in July, 33.8 here, 28.7 in September. Nothing about the timing within the month matters much.

Daylight in August

13.9 hours of daylight, losing 1.2 hours across the month. That is between Zaragoza's extremes of 15.2 and 9.2 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 31.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within August itself the daily swing is 15.2 °C, so mornings and afternoons need different clothes.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

August in Zaragoza versus nearby

If Zaragoza is one option among several, the nearby comparison is worth making. Gasteiz / Vitoria is a better bet in August — 9 °C cooler, 6 days more rain. Valencia is the weaker option in August — within a degree on temperature, the same number of rain days.

So: August is a compromise. October is 24 points better and is what Zaragoza is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
