The immediate context: at the peak of the operación retorno Spanish petrol stations are reporting markedly higher prices than at the start of the holiday period. According to the regularly updated figures from the Geoportal Gasolineras of the Ministry for the Ecological Transition (MITECO), on 23 August 2026 on Peninsula and Balearic Islands for diesel 1.875 euros per litre and for Gasolina 95 around 1.735 euros per litre were listed.
Compared with 1 July 2026, this represents a diesel price increase of up to 21 per cent. For an average 55-litre fill-up, this means paying almost 18 euros more.
The figures are based on the reported selling prices, which more than 11,000 stations are required to submit and which are published on the Geoportal and compiled in the open-data file “Precio de carburantes en las gasolineras españolas”. Context: Spanish media have reported a sustained rise in petrol and diesel prices since mid-August, during the holiday month. Higher wholesale prices and seasonal demand are cited as drivers; the publications consulted contain no reliable official figures for additional tax factors during the period under consideration.
In fact, the Geoportal Gasolineras datasets show an increase in both types of fuel compared with early July, with diesel rising more sharply than Gasolina 95. Significance: higher prices make personal travel more expensive, affecting commuters and holidaymakers alike and increasing ongoing costs for road freight. The Geoportal gives consumer protection bodies and regional authorities a closely updated view of reported selling prices, although individual stations may still charge different prices locally.
Methodological note: The Geoportal aggregates prices reported by operators; these are not official consumer price indices. Comparisons over time refer to the daily figures shown, in this case 23 August 2026 compared with 1
July 2026. The sources reviewed do not support forecasts for future price movements with reliable figures, so this remains uncertain. For people travelling during the current return traffic, the evidence points to clearly higher prices at the pumps.
