On the Balearic Islands expects the Agencia Estatal de Meteorología (AEMET) to bring mostly sunny and only slightly cloudy weather over the weekend of 12 and 13 September 2026. Temperatures will be slightly above the seasonal average. The forecast applies equally to Mallorca, Menorca, Ibiza and Formentera although daytime highs may vary from one area to another.
Despite the generally stable conditions, isolated showers are possible in places in the afternoon and early evening. Such precipitation may occasionally take the form of “lluvia con barro” (mud rain) if there is Saharan dust from North Africa in the upper layers of the atmosphere. The AEMET does not currently expect widespread rainfall or any prolonged, heavy rain events.
Winds will generally be light to moderate, from the east to north-east. Daytime sea breezes are expected along the coasts and may bring locally stronger winds. AEMET publishes separate marine forecasts for coastal and sea areas; based on the current picture, wave conditions and visibility are expected to remain generally favourable.
Some of the warmest areas of the island group could be subject to yellow heat warnings over the weekend. AEMET updates such warnings depending on the island and time of day, so they should be checked at short notice. Heat stress remains moderate across the islands; nevertheless, health services advise taking the usual precautions when exposed to direct sunlight.
Meteorologically, the settled conditions are underpinned by a high-pressure system dominating the western Mediterranean. The stable air masses favour plenty of sunshine, while weak pressure gradients do not entirely rule out local showers. Forecasts depend on the models used, so slight shifts in the location and timing of possible showers are normal.
The AEMET forecast covers the Illes Balears and was updated on Friday. Statements on rainfall and warning levels are forecasts and may change at short notice. The official AEMET coastal forecast provides specific information for individual stretches of coast, bays and ports.
Places and islands affected: Mallorca, Menorca, Ibiza and Formentera. The Agencia Estatal de Meteorología (AEMET) is responsible for the official weather situation.
