Været i Cambridge i desember

London's December threads settle on an average around 6°C, a high chance of rain, and darkness closing in by about 4pm. Regulars rate it milder than January or February, and they're clear about timing: the Christmas feel is best from roughly 1 to 21 December. After that it turns awkward — no public transport on the 25th, shops shut, many attractions closed, and Christmas Day meals priced accordingly.

Regulars are specific this month brings the Backs along the River Cam carpeted in crocuses and daffodils, punting season properly underway with shorter queues than summer even though the weather itself stays genuinely hit-and-miss. Our row backs that cool, genuinely dry read, 14.3C over 4.3C nights feeling 1C, with rain light at 25.9mm across 6.6 days and humidity at 75 percent. Regulars are consistent real rain and river swell can occasionally cancel a punting trip outright, layers, a light waterproof jacket and comfortable shoes the standard advice regardless. The city and river stay noticeably quieter than the following July and August, a genuine upside for anyone prioritizing a relaxed walk over crowds. The record: 9.4 hours of sun, humidity 75 percent and a 20.4 kph wind.

The most useful thing about May here has nothing to do with weather: exam term closes most colleges to visitors from about the middle of the month until the middle of June, so the courts everybody comes to see are shut to let students revise. A few of the large ones keep their chapels open, King's especially; each college lists its own access, and with thirty-one of them something is always open. The answer regulars give anyway is to take to the river - punting the Backs passes Queens', King's, Clare, Trinity and St John's without setting foot inside any of them. That makes the forecast worth watching: our row reads 17.8C but feels 16C in a 19.6 kph wind, with 7.9C nights and 46mm of rain across 7 days. The record: humidity 75 percent, 10.2 hours of sun and AQI 41.

Regulars name the dates to avoid rather than the weather to expect. The weekend term begins is the worst of the month and the week before it is already filling, because freshers arrive early and returning students earlier still; the Duxford airshow adds traffic in the middle of September. They rate September over October - statistically warmer and drier, and the days longer - while conceding the weather is as changeable as ever, with mild days, clear evenings and a snap of autumn. This is an outdoor city of parks, gardens, courts and punts, so pick a decent day and avoid a weekend. Our row: 20.3C over 11.2C, 50.3mm across 8 days, 7.7 hours of sun and a 20.9 kph wind.

The single most useful thing regulars tell a June visitor is that May Week is in June - usually the last fortnight, with most college balls around the week of the 19th - and that colleges close to the public while they set up or clear away. Late June is also the main graduation season, so parts of town are packed on those days and restaurants want booking. For punting, go early, before the coach tours: the Backs get very busy with punts through June and boats are worth reserving. Avoid Saturday, when the town is rammed. Our row is the driest British June in this collection at 54.6mm across 7.4 precipitation days, with 21.1C days, 11C nights and 16.7 hours of daylight. The record: humidity 73 percent, 10.5 hours of sun, a 19.7 kph wind and AQI 40.
