Spring has only just begun, but parts of Spain could soon get a taste of early summer. After the unsettled conditions linked to storm Therese, forecasts now point to a short-lived warm spell that could push temperatures close to 30C in some areas before the weather turns more changeable again.
La Razón reported on Saturday that the shift from recent cold and rain to much warmer conditions would be brief, with another drop likely afterwards.
Why is Spain getting warmer again after the latest storm?
AEMET’s latest extended outlook, published on 19 March, suggests the period from 23 March to 12 April is likely to be warmer than normal across Spain, especially in the first part of the forecast window. That does not mean a stable early heatwave is arriving, but it does support the idea of a short spring warm-up after a wet and unsettled stretch.
A sharp contrast after Therese
The change comes just after storm Therese brought a more unstable picture, with rain, wind and rougher conditions affecting parts of the country. Reporting this weekend said the storm’s effects were still being felt across southern Spain and the Canary Islands, with improvement expected at the start of the new week and more spring-like temperatures following behind.
That contrast is what makes this spell stand out. Spain is moving from a run of wetter, cooler weather into a brighter and warmer phase in the space of a few days.
Near-30°C in some parts, but not for long
The warmer air is expected to be most noticeable in southern and inland parts of the country, where temperatures could rise sharply for the time of year. La Razón said the jump towards 30 °C would be short, and that abrupt changes are likely to remain part of the pattern rather than signalling the start of prolonged heat.
That fits the broader seasonal picture. AEMET’s seasonal outlook for March, April and May 2026 gives a strong probability of above-normal temperatures across Spain, but that is not the same thing as saying every week will stay hot or settled.
A reminder that spring in Spain can turn quickly
This is the kind of weather swing Spain often sees in spring. One week can feel stubbornly wet and cool, the next almost summer-like, before conditions swing back again.
That makes this less a story about “heat arriving” than about the unstable rhythm of the season. For readers planning travel, terrace lunches or early beach days, the message is straightforward: enjoy the warmth, but do not assume it is here to stay.
What to watch in the coming days
The key point now is not whether Spain will warm up for a few days. It probably will. The bigger question is how long the milder pattern lasts before another cooler or wetter change moves in.
For now, the outlook points to a clear contrast with the recent stormy spell. Spring is beginning to look brighter, warmer and more inviting — but still very much like spring.
