Weather in Birmingham in January

The month to avoid. Of the twelve, January is the one to avoid. Highs sit at 6 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

January ranks 12 of 12 — near the bottom of Birmingham's year. August is the month that works, and the swing between the two is 46 points, which is a different holiday rather than a slightly better one.

This is persistent light rain rather than storms: 15 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Layers, and a genuinely waterproof outer — at 6 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: 13 nights fall below freezing; the day barely swings — 5.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 13.2 °C and the coldest night fell to -7.9 °C.

January is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest January on record still delivered 109 mm against 23 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 65 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 94%, which at 6 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How January sits in the year

Temperatures hold steady either side: 6.4 °C in December, 6 here, 6.9 in February. Nothing about the timing within the month matters much.

Daylight in January

January sits at the dark end of Birmingham's year — 8.2 hours of daylight against 16.8 at midsummer, gaining 1.2 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

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

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

January in Birmingham versus nearby

If Birmingham is one option among several, the nearby comparison is worth making. Manchester is close enough to be a coin toss — within a degree on temperature, 3 days more rain. London is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: January is a compromise. August is 46 points better and is what Birmingham is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
