Weather in Bordeaux in August
France · 20-year averages, August
Prime time. If you get to pick your dates, August is the one. Highs average 27.8 °C, lows 15.9 °C, and rain falls on 9 days — nothing in the month is working against you.
August ranks 4 of 12 in Bordeaux: past the worst of the year but short of July, which is the month to book if the dates are open.
Rain on 9 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
Averages flatten a month, and this one hides a few things: 8 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest August day reached 42.1 °C and the coldest night fell to 10.1 °C.
August is moderately variable: 12 mm in the driest year against 89 mm in the wettest, around an average of 46 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.
Wind is light at 6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 67%.
How August sits in the year
Temperatures hold steady either side: 27.4 °C in July, 27.8 here, 25.1 in September. Nothing about the timing within the month matters much.
Daylight in August
14.1 hours of daylight, losing 1.4 hours across the month. That is between Bordeaux's extremes of 15.6 and 8.8 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 25.2 °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.
August in Bordeaux versus nearby
If Bordeaux is one option among several, the nearby comparison is worth making. Toulouse is the weaker option in August — 2.3 °C warmer, 1 day more rain. Bilbao is close enough to be a coin toss — 3.7 °C cooler, 1 day less rain.
So: August is effectively as good as it gets here — 3 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
