Weather in Birmingham in August

A good month. August is a solid month to be in Birmingham. Highs average 20.3 °C, lows 11 °C, and rain falls on 14 days — nothing in the month is working against you.

August is the highest-scoring month of the twelve. The nearest rival is September, and the month at the other end of the year is January.

This is persistent light rain rather than storms: 14 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. 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: it never really gets hot: not one day in an average August reaches 30 °C. Across the twenty years measured, the hottest August day reached 30.3 °C and the coldest night fell to 5.2 °C, and the wettest single day dropped 27 mm — roughly 38% of the month's rain in one day.

August is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest August on record still delivered 131 mm against 21 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 72 mm average is a reasonable planning figure, not a promise.

Wind is light at 10.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.

How August sits in the year

Temperatures hold steady either side: 20.6 °C in July, 20.3 here, 18 in September. Nothing about the timing within the month matters much.

Daylight in August

14.8 hours of daylight, losing 1.8 hours across the month. That is between Birmingham's extremes of 16.8 and 7.7 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 19.9 °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 Birmingham versus nearby

If Birmingham is one option among several, the nearby comparison is worth making. Manchester is the weaker option in August — within a degree on temperature, 5 days more rain. London is close enough to be a coin toss — 2.3 °C warmer, 2 days less rain.

So: August is the answer for Birmingham. If it is booked out or priced out, September is the next best thing at 1 points behind, and January is the month to keep off the shortlist.
