Weather in Ibiza - Spanish Holiday Islands Mediterranean

It is entirely fitting that Ibiza's famously stunning sunsets, whether enjoyed at the perennially popular Café del Mar or at the secluded Cala Conta, should be preceded almost all the year round by hot, cloudless days. On average, Ibiza enjoys between five hours of sunshine per day, in November and December, to an astounding twelve hours of sunshine per day in the height of summer. There are around 300 days of sunshine every year. It is a reassuring fact that the weather in Ibiza is nothing if not predictable.
The best Ibiza weather tends to come in August, the hottest month, when the average daily temperature is 29 degrees Celsius. Nevertheless, the average daily temperature remains well into the 20s from early May until late October, and generally dips no lower than a perfectly pleasant 15 degrees during the coldest months of January and February, and seven degrees at night. It is rarely so cold in Ibiza that the outside temperature becomes uncomfortably chilly.
In the height of the tourist season, in July and August, Ibiza gets on average one day of rain per month. Even in the autumn and winter, the highest monthly rainfall average is seven days - in October - with spring tending to see no more than three days of rain per month.
By far the most miserable months for weather in Ibiza are January and February, and the most clement are July and August. Although these summer months can get very hot indeed, the heat is rarely arid or stifling; the surrounding sea and its attendant breezes ensure that there is always a slight wind. If all else fails, the cooling sea itself is never more than 10 kilometres away.
The fact that Ibiza weather is basically glorious all year round means that there is no real need to visit the island in the middle of the manic tourist season - unless, of course, the purpose of your visit is to live it up with the international crowds on the dancefloors across the island. Ibiza is a lovely place to spend the winter, and the Easter holidays can often be as hot as August.
The only downside of all this is that the islanders are so geared up to make life one big party from May until September that the rest of the year tends to be remarkably quiet on Ibiza. Unless you are going in order to visit remote beaches and traditional, local restaurants, you may find yourself admiring the springtime sunshine in what appears to be a ghost town.
