Weather in Gijón in August

Prime time. If you get to pick your dates, August is the one. Highs average 25.7 °C, lows 17.5 °C, and rain falls on 9 days — nothing in the month is working against you.

August ranks 2 of 12 in Gijón. Only July scores clearly higher, and the difference is small enough to be settled by price rather than weather.

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

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest August day reached 37.4 °C and the coldest night fell to 13.2 °C, and the wettest single day dropped 26 mm — roughly 65% of the month's rain in one day.

August is moderately variable: 14 mm in the driest year against 89 mm in the wettest, around an average of 40 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 8.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How August sits in the year

This is a turning point in the year — July and September sit on opposite sides of it, so the month contains the change rather than following it.

Daylight in August

14 hours of daylight, losing 1.3 hours across the month. That is between Gijón's extremes of 15.4 and 9 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 20.9 °C in August — swimmable, but it takes a moment to commit. This is the warmest the water gets all year.

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 Gijón versus nearby

If Gijón is one option among several, the nearby comparison is worth making. Valladolid is close enough to be a coin toss — 5 °C warmer, 6 days less rain. Bilbao is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: August is effectively as good as it gets here — 2 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
