A day in Huelva: Spain records hottest ever Sept temperature just days before the Vuelta peloton rolls through

Five days ago, Spain's state weather agency AEMET recorded a temperature of 45.7°C in El Granado, in the southwestern province of Huelva. It was the joint-highest September temperature in the country's recorded history and the highest reading anywhere in Spain so far this year. On Tuesday, the Vuelta a España returns from its second rest day for Stage 16. The entire 181.1 kilometre stage runs through Huelva province. As the heat crisis continues to grip the 2026 Vuelta a España, the decision to continue (unchanged) will likely spark even more questions and protests from the cycling world.

The 45.7°C in El Granado was measured at 16:20 on September 3 and matched Spain's September temperature record, previously reached in Montoro, Córdoba, in 2016. But the context around it makes the reading far more alarming. On the same day, AEMET announced that the country had experienced its hottest January-to-August period on record, 'with a clear difference' when compared with the next four warmest periods, all recorded in the previous four years.

AEMET described the pattern as 'an unmistakable sign that warming is accelerating in Spain.' The agency also briefly issued the highest red alert for heat in small areas of Andalusia that Thursday, the first time such warnings had been sent in September since they started in 2007.

The timing is itself striking. Spain endured repeated periods of extreme heat during June, July, and August, yet none produced an official station temperature higher than the one measured during the first days of meteorological autumn. Several other locations in Andalusia exceeded 44°C on September 3, including 45.1°C at Sevilla Tablada, 44.7°C at Fuentes de Andalucía, and 44.5°C in Andújar.

Cortegana lies at an altitude of around 650 metres, and the route heads south on winding terrain for the first half of the stage, rolling through the Sierra de Aracena and Picos de Aroche national park before flattening out toward the coast, with the finish located at La Rábida, a Franciscan monastery in Palos de la Frontera.

The race jury has confirmed that the exemption on feeding rules will apply to stages 16 and 17, allowing teams to feed along the entire route and from the team car. The same measure was granted for stages 14 and 15 after the extreme heat of the second week. Stage 15 was originally planned to cover 189.7 kilometres but was cut to 110.2, and its start was delayed by two hours.

Riders and teams have been vocal about the conditions throughout the second week. Matthew Brennan sharply criticised the UCI, and race leader Enric Mas acknowledged that unnecessary risks could not be taken.

Those complaints came during a week when Spain's weather agency was simultaneously recording the country's highest temperature of the year in the same province the peloton will cross on Tuesday.

The heat taking a toll on the Vuelta has exacted an even greater cost across Spain as a whole. According to the MoMo mortality monitoring system, 5,232 deaths have been statistically linked to high temperatures in 2026, the highest figure since the system was launched in 2015. In August alone, MoMo estimated that 2,149 deaths were attributable to high temperatures.

Some respite is on the way apparently, with many heat alerts across southern Spain downgraded to yellow, and temperatures in the Huelva area are expected to settle in the mid-30s. But the Vuelta continues through Andalusia for the rest of the week, with Stage 17 heading to Seville on Wednesday and the individual time trial in Jerez de la Frontera on Thursday. By every available measure, the heat that has defined this race is part of something much larger.
