Palma (Mallorca) sää — tammikuu

Forum posters describe January as genuinely unpredictable - one day mild enough to sit outside in shorts at midday, the next brought down by the tramontana, the notoriously fierce northerly wind the island is historically known for, cold enough to need a proper fleece. Buildings here are generally built to stay cool in summer rather than warm in winter, so posters recommend checking for real heating (not just a token heater) before booking January accommodation. The wind risk is genuinely uneven across the island - posters specifically warn against staying in exposed northern spots like Es Grau, Mesquida or Arenal d'en Castell during December-February, recommending the more sheltered main towns (Mahon, Ciutadella, Alaior, Es Castell) instead for a more comfortable winter stay.

Regulars are direct that this technically counts as the wettest month of the year on the island, electrical storms and heavy downpours genuinely possible, though they're specific these tend to be measured in hours rather than days - rain overnight, clear and sunny again by lunchtime is a common pattern. Our row backs that warm, still-showery read, 25.4C over 16.4C nights, with 67.7mm of rain across 5.7 days and humidity at 76 percent. Regulars are consistent evenings start turning noticeably chillier as the month progresses, a real shift from the deep-summer warmth just weeks before. The sea sits at a warm, still-swimmable 24.4C despite the cooling air. The record: 9.4 hours of sun, a 17.5 kph wind and AQI 41.

Regulars call this month generally settled and stable, low-to-mid-20s and sunny with at most the occasional cloudy day or odd shower, though they're honest that a genuine outlier exists - one visitor's entire week of rain in May is cited alongside the more typical lovely-every-day experience others report. Our row backs the mostly-settled read, 24.6C reading as 26C over 15.4C nights, with 31.7mm of rain across 3.3 days. Regulars name this and June as offering warm weather without summer's extreme heat or crowds, a genuine off-season sweet spot. The sea is still on the cool, refreshing side rather than warm at 20C. The record: humidity 71 percent, 12.7 hours of sun, a 17.2 kph wind and AQI 47.

Palma-forum threads on September weather call it a genuine sweet spot: still warm enough for the beach and both the pool and sea, but with the harshest edge of August's heat gone, especially by the back half of the month. Early September can still run hot, mid-to-high 20s or higher, cooling gradually as the weeks pass toward a milder but still entirely swimmable late-September. An occasional thunderstorm is called normal for the month, but posters are consistent it's short and sharp rather than a multi-day washout, genuinely unusual to see back-to-back rainy days. One specific upside regulars mention: UV levels drop enough by September that tanning without burning gets noticeably easier than in peak summer. Evenings do call for a light layer, cooler after dark than the daytime warmth suggests. The record: 29.1C days feeling like a punishing 31C, 20.2C nights, 56mm across 5.2 days, a 26.5C sea, 73 percent humidity and 10.6 hours of sun.

August is the month the Palma forum warns people off, and their summary is four words: too hot, too humid, too busy, too expensive. Our row gives 32.5C reading as 35C, with regulars reporting upper 30s and low 40s and a seafront thermometer at 44C in one heatwave. The humidity is what they say ruins the evenings, which is the part visitors do not plan for. On crowds, this is peak season twice over - the European holiday month and the month mainland Spaniards come across - and one account has two hours to get in and out of the city. The beach with a breeze is tolerable; walking the city is not. June is the alternative they name. The record: 23.2C nights, 1.3 precipitation days and a 28.1C sea.
