Noter fra rejsende om Belfast i oktober
Noter fra Dublin i nærheden (142 km væk)
Belfast har ikke sine egne noter for oktober endnu — disse handler om Dublin, tæt nok på til at dele sæsonen.
Dublin forum regulars call October genuinely unpredictable but manageable: cool, “10-12 degrees C on average, though you can get peaks to about 20 degrees C,” with rain which can be occasionally heavy, and “it can rain at the drop of a hat and then be sunny and clear just minutes later.” Layering is the standard advice — a waterproof outer layer with warm layers underneath — since a day can run warm and turn “very cold the next.” Daylight shortens fast, dark by around 6pm. The trade-off regulars name for the unsettled weather: noticeably fewer crowds and cheaper accommodation than summer. Our record: 13.9°C days, 9.7°C nights, 16.2 rain days and a 24.4kph wind — cool and wet more days than not, backing the “occasionally heavy” read more than the milder framing.

Regulars are specific that National Trust properties around the region start reducing their opening hours this month as the summer season winds down, a real planning detail beyond the weather itself for anyone timing day trips out of the city. Our row backs that mild, genuinely wet read, 17.5C over 10.7C nights feeling 9C, with 80.3mm of rain across 12.7 days and humidity at 82 percent. Regulars are consistent the city itself thins out noticeably once summer tourists head home, easier hotel availability a real upside to the increased rain risk. Layers and a proper rain jacket remain the standard advice regardless of which week a visit lands on. The record: 7.3 hours of sun, a 21.5 kph wind and AQI 35.
Regulars rate May over Easter here on two counts - better odds on the weather, and a month outside the marching season, so nothing to plan around. They are honest that the odds are only odds: one contributor remembers a grey, cool, wet May, and they describe the local climate as erratic with summers that are mild rather than warm. Our row is the temperate middle of that, 17.2C reading as 15C in an 18.5 kph wind, 8.5C nights, and 51.1mm of rain across 10.7 days. What May reliably gives is 16.1 hours of daylight, which is what makes the coast road north worth a whole day. The record: humidity 78 percent, 10.6 hours of sun and AQI 40.
August is among the warmest months here and regulars put it at 16 to 18C, a little under our row's 19.7C, with the streets noticeably busier than in the cold half of the year. On rain they are matter-of-fact rather than apologetic: this is a temperate climate, it rains through the year, and the one item never to leave at home is a rain and wind jacket. Our row is blunter than their word for the north and east coast, relatively dry - 87.2mm across 14.4 days, so rain falls on close to half the days of the month, though 8.9 hours of sun fall inside 14.9 of daylight. The record: 12.5C nights, humidity 82 percent, a 19.6 kph wind and AQI 30.
Belfast regulars answer the June question with a range and a shrug: usually 15 to 22C, and it could be sunny, cloudy or wet, because the weather here is erratic and summers are mild rather than warm. Our row's 19.3C over 11.3C sits in the middle of their range and reads as 18C once the 18.7 kph wind is counted. What they promise instead of warmth is light - at this latitude in June it is not properly dark until around eleven at night, which our row's 17.2 hours of daylight bears out, and it makes long evenings the best part of the day. The packing list never changes: layers, and a mac or a pacamac whatever the month. The record: 74.3mm across 11.8 precipitation days, humidity 79 percent, 10.2 hours of sun and AQI 38.
