Het weer in Ibiza (Eivissa) in juni

June is the month Ibiza regulars name as the most reliable for weather - long days, the least chance of rain in the year, which our row puts at 1.2 precipitation days and 8mm - with a cardigan for the evening the only concession. The season is the other half of the answer, and it turns inside the month. Early June is quiet, with the opening parties on but the clubs not really running until mid-June, after which the crowds build; you still get nothing like July and August. One regular's phrase for early June is being the first person to arrive at a party, and the bonus they point out is service, because the hotels, bars and restaurants are fresh. The record: 27.5C days that feel like 28C, 18.8C nights, 13.5 hours of sun and a 23.9C sea.

Ibiza-forum threads on December weather are consistent that the sea is firmly off the table for swimming - cold enough that even a quick dip isn't appealing - while daytime air temperatures can still climb into the high teens or low twenties Celsius in full sun, a pleasant surprise for visitors expecting a harsher winter. Nights run genuinely cold, into the upper single digits Celsius on the coldest stretches, and wind is a regular feature that makes it feel colder still. The clubbing season that defines Ibiza's summer reputation is entirely dormant by December, but posters frame this as an upside: deserted beaches, the countryside at its most beautiful, and the island's best restaurants still open at off-season prices. Rain shows up on a good number of days without ever being described as a washout. The record: 17.3C days feeling like 15C, 8.8C nights, 38mm across 4.4 days, a 17.5C sea, 73 percent humidity and wind averaging over 23 km/h.

Ibiza-forum threads on April weather describe a genuinely lovely but not-quite-summer month: warm in sheltered, sunny spots, properly cool the moment wind picks up or the sun dips, and evenings cold enough that regulars pack jeans and a jumper alongside their shorts. The sea is the clearest giveaway that summer hasn't arrived - still cold enough for only a brief dip, nowhere near warm enough for a young child to splash around comfortably for long. Posters call April and May, together, the best stretch of the year for a certain kind of visitor: crisp air, plenty of sun, cooler nights, and beaches that stay genuinely uncrowded before the summer season takes over. The standing advice is simply to dress in layers and treat the sea as scenery rather than a swimming destination this early in the year. The record: 19.5C days feeling like 18C, 11.5C nights, just 31mm across 4.6 days, a chilly 17C sea, 66 percent humidity, 11.2 hours of sun and wind averaging nearly 24 km/h.

Ibiza-forum threads on September describe a real handoff: the crowds of August thin out fast, most Italian visitors gone by the end of the first week, and by the last week the island runs genuinely quieter and calmer - San Antonio and Ibiza Town stay busy but without August's crush or prices. Weather-wise, posters call September and October among their favorite months, typically great, though end-of-summer storms do roll through and an occasional torrential downpour is part of the deal, usually short-lived rather than ruining the day. The overall vibe shifts too - relaxed, closing parties across the clubs, free parties filling the gaps. The record: 27.8C days feeling like 30C, 19.9C nights, 76mm across 4.5 days, a 26.7C sea, 67 percent humidity and 10.7 hours of sun.

July and August are the two months regulars will guarantee a warm sea, and July is the one they pick of the pair if the clubbing is the point. It is hot - the countryside burns off by midsummer and some visitors find the middle of the day too much to be out in - with the sea breeze doing the work, and evenings that stay very warm. The crowd is not spread evenly: one early-July report has the beaches manageable and the clubs packed. If avoiding people is the aim, the advice is the blunt one, which is not to come in July or August at all. The record: 30.3C days that feel like 32C, 22.1C nights, 0.5 precipitation days, 13.4 hours of sun and a 27.9C sea.
