Weather in Stavanger in August

Shoulder season. August sits in between. You will get good days and you will lose some. You should expect rain on 19 days of the month, which is more days wet than dry.

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

Rain on 19 days, 5 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 17.8 °C days and 13.9 °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: the day barely swings — 3.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest August day reached 26.5 °C and the coldest night fell to 8.9 °C, and the wettest single day dropped 62 mm — roughly 41% of the month's rain in one day.

August is one of the reliable ones — rainfall has stayed between 93 mm and 207 mm across all twenty years, a narrow enough band that the 150 mm average is something you can plan against rather than merely quote.

Wind is light at 11 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How August sits in the year

Temperatures hold steady either side: 17.6 °C in July, 17.8 here, 15.1 in September. Nothing about the timing within the month matters much.

Daylight in August

15.6 hours of daylight, losing 2.4 hours across the month. That is between Stavanger's extremes of 18.4 and 6.3 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 17.2 °C between the year's warmest afternoons and coldest nights.

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 Stavanger versus nearby

If Stavanger is one option among several, the nearby comparison is worth making. Kristiansand is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Bergen is close enough to be a coin toss — within a degree on temperature, 3 days more rain.

So: August is effectively as good as it gets here — 1 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
