Погода: Роттердам, июнь

One regular answered a June question here by looking up a single date: on the 16th the average maximum is 20C, the record range runs from 13C to 25C, and it rained on nine of the last twenty. That is the honest shape of a Dutch June. Our month averages 22.5C over 12.1C with 70.2mm across 8.9 days, so rain on roughly three days in ten rather than his four-and-a-half. The compensation is light - 16.7 hours of daylight with 11.5 of sun - which is what makes June the month for day trips out of the city and for the canal-level terraces this town is known for. An 18.5 kph wind keeps it fresh. The record: humidity 74 percent and AQI 49.

Forum posters describe January across the Netherlands, Rotterdam included, as capable of almost anything - temperatures anywhere between -15C and 15C, with varying degrees of rain, snow, or clear skies possible on a given day. Posters consistently recommend a proper winter coat, hat, scarf, gloves, warm sweaters and genuinely warm, weatherproof footwear regardless of forecast. Posters are direct that snow isn't guaranteed, and even when it does fall it typically doesn't stick around for long. Posters generally caution that forecasts here are only reasonably reliable about 2-3 days out, so treating a longer-range prediction as certain is a mistake. Posters generally rate January as workable for a Rotterdam visit with the right packing, but genuinely unpredictable day to day.

The Dutch line the forum keeps quoting for July is "if you don't like the weather, just wait five minutes" — and the numbers bear it out: around 22°C on average, but posters describe 28°C one day and 15°C the next, and sunny mornings turning to thunder by the afternoon. Rain lands on about thirteen days. Layers plus a small umbrella or poncho is the standing advice, with a big thin scarf as the adjustable extra. July is also crowded and pricier once the school holidays start. Rotterdam-specific: the bike paths, the harbour boat tours, Delfshaven and the water taxi all survive a shower.
