Weather in Kingston upon Hull in September

Prime time. September is about as good as Kingston upon Hull gets. Highs average 18.5 °C, lows 9.7 °C, and rain falls on 10 days — nothing in the month is working against you.

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

Rain on 10 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: it never really gets hot: not one day in an average September reaches 30 °C. Across the twenty years measured, the hottest September day reached 27.5 °C and the coldest night fell to 3.1 °C, and the wettest single day dropped 25 mm — roughly 48% of the month's rain in one day.

September is moderately variable: 17 mm in the driest year against 96 mm in the wettest, around an average of 52 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 11.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How September sits in the year

The month is on the way down: 2.4 °C cooler than August, with October dropping another 4 °C. The first week and the last are not the same trip.

Daylight in September

12.8 hours of daylight, losing 2.1 hours across the month. That is between Kingston upon Hull's extremes of 17 and 7.5 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 14.4 °C in September — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. 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.

September in Kingston upon Hull versus nearby

If Kingston upon Hull is one option among several, the nearby comparison is worth making. Manchester is the weaker option in September — within a degree on temperature, 5 days more rain. Birmingham is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: September is the answer for Kingston upon Hull. If it is booked out or priced out, August is the next best thing at 3 points behind, and January is the month to keep off the shortlist.
