Burgos is about to get a blast of summer just as autumn begins. Temperatures will shoot past 30 degrees, skies will stay clear, and rain is nowhere in sight.
This week, Burgos is set to ignore the calendar. Temperatures will jump far above what’s normal for late September. The province faces a run of heat that feels more like July than autumn. As autumn officially starts, the veranillo de San Miguel is hitting hard. Dry, stable air is moving in, and daytime highs will top 30 degrees in many places.
The Agencia Estatal de Meteorología (Aemet) says Burgos city will get hotter each day. By Thursday and Friday, the mercury could hit 33 degrees. Nights won’t cool things down much, with lows between 10 and 14 degrees. That means chilly mornings but blazing afternoons. There’s no real rain coming, so the dry stretch that started after a record August will drag on. Aemet reports this summer was Spain’s hottest since records began in 1869. The average temperature was 24.5°C, which is 2.4°C above the 1991–2020 average.
On September 9, Spain activated a red heat alert for the first time ever in September, marking an unprecedented level of risk for this time of year.
In the Ribera del Duero, Aranda will see the same pattern as the capital. Skies will stay clear, the sun will beat down, and highs will stick between 31 and 32 degrees. Early mornings might drop to 9 degrees, but the heat will come back fast. No rain is expected. The air will be still, with barely any wind to break up the heat.
Miranda de Ebro is bracing for even higher temperatures. Forecasts show peaks of 35 degrees on Thursday and Friday. Nights will be cool, between 9 and 13 degrees, but the swing between day and night will be sharp—sometimes more than 20 degrees. Skies will stay mostly clear. The wind will be weak, making the heat feel even stronger during the day. Aemet has kept yellow and orange heat warnings in place for several autonomous communities, including Castilla y León, because of the ongoing high temperatures.
Both Aemet and Meteored say this week’s heat will run more than four degrees above the seasonal average. There’s a real chance new records could be set. The veranillo de San Miguel, which usually brings a short warm spell around September 29, is stronger than usual this year. The heatwave is spreading across Burgos and much of Spain.
Aemet has reported that Spain experienced 61 days of heat waves on the Iberian Peninsula and Balearic Islands in 2026—a record since 1961. The agency also forecasts a 60–70% probability of above-normal temperatures across Spain for September to November, suggesting the warm anomaly is likely to persist into autumn.
Some relief could come after the weekend. Meteored says cooler air and maybe a front could arrive from Sunday. That would bring lower temperatures and a shift to more unstable weather. Until then, rain will stay away, and the hot, dry pattern will rule daily life in Burgos.
This stubborn heat at the start of autumn is more than just a weather oddity. It shows how the seasons are shifting, with old patterns breaking down. For people and farmers, the lack of rain and long stretch of warmth bring real problems, from water shortages to daily discomfort. As Burgos sweats through this late heat, the province is once again left waiting for the weather to change.
