カプリ島には4月のメモがまだありません — これは季節を共にする近くのソレントについてのメモです。
Sorrento-forum threads on April weather describe it as genuinely fickle - one day pouring with grey skies, the next gorgeous and blue, sometimes within the same visit. Regulars call April normally fresh and showery, sunny days pleasant but outnumbered by cooler, damper ones, and evenings cold enough that a jacket is non-negotiable even after a warm afternoon. The standing packing advice is layers throughout: linen or light trousers with a top for daytime, a proper sweater or cardigan for evenings, plus a real waterproof rather than a light showerproof. Despite the variability, most posters still call April a lovely month overall, just one where a week's stay is likely to see both extremes rather than a single settled pattern. The record: 18.8C days feeling closer to 19C, 13.3C nights, 57mm across 9.7 days, a chilly 15.6C sea still too cold for most swimmers, 74 percent humidity and 11.1 hours of sun.
カプリ島のほかの月
Asked whether late May is swimming weather, regulars say the sea is still cold and some people go in anyway; our column reads 18.9C, which is exactly that answer in a number. What they are firmer about is the boats. The island is already busy in May, the day-trip crowd arrives mid-morning, and the two rules are to come on the earliest ferry and to avoid weekends - the little beach below the town is full by late morning. Air is gentler than the sea at 21.2C reading as 22C, over 15.6C nights, with 76.3mm of rain across 10 days and 11.9 hours of sun. The record: humidity 76 percent, a 16.1 kph wind and AQI 68.
Capri-forum threads asking if August is worth it land on a split verdict: the weather itself is genuinely excellent, the summer pattern of sun and heat holding steady with only the occasional thunderstorm, but posters are blunt that the island turns properly overwhelmed with visitors, since much of Italy takes its own summer break at the same time. The port at Marina Grande is described as packed on arrival, and regulars recommend the earliest possible ferry plus heading straight up to Anacapri ahead of the day-trip crowds. Weekends specifically get singled out as the worst days to attempt a visit. Swimming conditions are called some of the best of the year regardless, warm seas and long, sunny days more than making up for the crowds if timed around the busiest hours. The record: 29.3C days feeling like a punishing 32C, 23.4C nights, just 27mm across 5.2 days, a 25.6C sea, 69 percent humidity and 12.3 hours of sun.
Capri-forum threads on June timing draw a clear line at mid-month: early June is repeatedly rated the better window, before the day-trip ferries start packing the Piazzetta, the funicular and the bus stops with crowds that run heaviest from mid-June through early September. One poster's early-June trip felt less crowded than a late-July visit; by contrast a late-June day trip is described as a conga line off the boat. The Blue Grotto is weather-dependent too - it closes whenever the sea is too rough, so build in a spare day if it's the priority. June's record: 26.2C days feeling like 29C, 20.6C nights, four rainy days, 13.4 hours of sun and a 24.1C sea - the start of the island's warm-water stretch that runs into October.
Capri forum regulars call March a genuine improvement on January and February — “nice enough to walk around in long sleeved t-shirts without a jacket during the day...but cooler at night” — while warning March and April can “change from day to day.” The trade for that mild-but-unsettled weather is real: a lot of restaurants and activities are still closed for the season, locals call it their favorite month specifically because of that quiet, and posters note you'll have parts of the island genuinely to yourself. The Blue Grotto is a coin flip, open or closed depending on sea conditions rather than the calendar. Our record: 12.6°C days, 7.9°C nights, 10 rain days and 0.4cm of snow — cool and unsettled, matching the day-to-day variability the forum describes more than a single reliable read.

- ルール
Landing fee on arrival
1月1日〜12月31日Everyone who is not a resident pays a landing contribution on arrival: about €5 a person from April to October and €2.50 the rest of the year. On a scheduled ferry or hydrofoil it is inside the ticket; on a private boat it is not. 出典 ↗
- ルール
No visitor cars on the island
3月15日〜11月5日 · 例年休業Non-resident vehicles are barred from the island from around Easter to early November, which is why everything moves by funicular, open taxi and the Anacapri bus. Bringing a car is not a decision you get to make. 出典 ↗
- 祝日
Easter and Pasquetta
4月4日〜6日イースター・聖週間混雑休業Easter Sunday and Easter Monday (Pasquetta) are public holidays, and Italians use the long weekend for short breaks and day trips: trains and hotels fill, old towns and sights are busier than the weeks around, and many shops and some restaurants close on Easter Sunday. 出典 ↗
- オープン
Island season opens
3月25日〜5月15日 · 例年夏季営業スタートHotels, the Marina Piccola beach clubs and the full ferry timetable restart around Easter. April and early May are the only weeks when everything is open and the paths are still empty. 出典 ↗
- 自然
Broom and cistus on the paths
4月5日〜5月25日 · 例年野の花・花の見頃The Sentiero dei Fortini and the walk up Monte Solaro are at their best when the broom and rock rose are out, before the day boats arrive in numbers and while the light is still soft. 出典 ↗
- オープン
Blue Grotto access
4月15日〜10月15日 · 例年休業The cave entrance is barely a metre high at low tide, so a boatman can only lie you flat and row you through when the sea is calm enough; rough winter seas suspend the trips for days or weeks at a stretch even though the site itself has no fixed closing date. 出典 ↗
- 祝日
Spring bank-holiday bridges
4月25日〜6月2日国民の祝日混雑早めの予約をLiberation Day (25 April), Labour Day (1 May) and Republic Day (2 June) are public holidays, and when one falls near a weekend Italians bridge it into a long break, the ponte. Those weekends bring domestic crowds, fuller trains and higher room rates, and some shops close on the day. 出典 ↗
