מזג האוויר בליברפול בספטמבר

Regulars put late September here at 10 to 17C with cooler evenings and rain expected, and our row lands on exactly that: 18.1C by day feeling 17C, 10.4C at night feeling 9C in a 20.4 kph wind. Their instruction is layers rather than one coat - a thin jumper, a thicker one, and a light top layer that keeps water out. On how much rain, the honest arithmetic is worth having: 96.4mm across 14.4 days is under seven millimetres a day, so the city's reputation is built on how often it rains rather than how hard. Sun is down to 7 hours inside 12.7 of daylight and humidity is up at 83 percent. The record: a dew point of 11C and AQI 39.

Regulars describe temperatures in the high 40s, 50s or low 60s Fahrenheit with showers likely most days, and specifically recommend checking a proper forecast the week before rather than trusting any seasonal generalization given how unpredictable UK weather can be. Our row backs the cool, damp read, 13C reading as 10C over 6.2C nights feeling 2C, with 61.6mm of rain across 11.6 days and a trace of leftover snow, 0.2cm, alongside a real 24.6 kph wind. Regulars are consistent on the standard packing list: waterproof shoes, a light jacket over real layers, and a fleece or jumper for the chillier stretches. The sea stays cold at 10.1C. The record: humidity 76 percent, 9.9 hours of sun and AQI 39.

May carries two bank holiday weekends, which regulars mention for the practical reason - the city is busier and the rooms are dearer on both. Their packing answer is the usual northern one and our row supports it: 16.6C reading as 14C in a 22.5 kph wind, nights at 9.5C, and 60.5mm of rain across 11.3 days, so a warm jumper under something waterproof and breathable. What May gives back is light, 15.9 hours of it with 11.4 of sun, the best ratio of the year so far. One local tip worth the effort: the walk out to Hilbre Island across the sands runs on the tide, so check the times before setting off. The record: humidity 76 percent and AQI 44.

The advice here is a t-shirt with a sweatshirt over it for evenings and cooler days, plus something waterproof and light - and a note that what rain comes in early summer is usually light and evaporates almost at once. One regular counted rain on five days out of twenty-eight. Our row says 15.4 rainy days, and both are right: 93.5mm across those days is about six millimetres each, so most of them are a shower that dries before you have found the cafe. Temperatures run 19.2C by day over 12.4C at night, feeling two degrees cooler because of a 23.1 kph wind off the Irish Sea. Daylight is the compensation at 16.9 hours. The record: humidity 76 percent, 11.6 hours of sun and a 19.1C sea.

Liverpool-forum threads on July weather are candid that it's impossible to predict: rain, sun, wind and cold are all in play, and one poster's four-year sample of the first week of July found temperatures ranging from 16C to 29C with light rain on just a few of those days. The standing advice is layers plus a proper waterproof rather than an umbrella, breathable fabrics for the warm stretches, and one smarter outfit saved for an evening out - and even on a genuinely warm day, more than one thread warns the breeze off the Mersey can catch you out. The record backs the unpredictable read: 20.2C days, 14.1C nights, 103mm of rain spread across a notably high 17.2 days, 10.9 hours of sun and an 18.1C sea - July here is real summer with plenty of it falling.
