Weather stations and what to measure on site: variables, sensor exposure and how to read official forecasts and bulletins alongside your own series.
On 31 October 2026 AEMET and the SMC published an analysis of the Montseny summit series, which joins two sites and fills the gaps from 2001 to 2010. What it teaches anyone planning to move a station or change a sensor.
AEMET expects a week that will probably be warmer than normal in southern Spain, with possible night frosts inland in the north and the heaviest rain in the Mediterranean area and the Balearics. Four official signals, including the new regionalised seasonal forecasts, and what to measure with each.
On 27 October 2026 the European Commission proposed the European Climate Resilience Law, with a reference global warming trajectory and periodic risk assessments. What that information describes, what it does not describe about your site and what is worth recording.
AEMET expects a settled week with temperatures high for the time of year and scant rain, and more uncertainty from 2 November. Four signals and what to check in your series, starting with the time: on Sunday 25 October, official time in mainland Spain and the Balearic Islands went from UTC+2 to UTC+1.
The week's four pieces (water level, frost, the warmest September and dendrometers), three European signals with their sources (ECMWF's open 9 km data, AEMET's analysis of the Catalonia rainfall and drought according to the JRC) and what is coming: the end of summer time on the 25th and the MARS Bulletin on the 26th.
AEMET reported on 16 October 2026 that September was the warmest in mainland Spain since 1961; according to the accompanying advance summary, average maxima were 4.6 °C above normal and average minima 2.1 °C above. What to check in your own series before comparing it with official figures that are still provisional.
AEMET has a special warning in force for very heavy, persistent showers on the Spanish Mediterranean coast and the Balearic Islands until Monday, with a risk of flash floods, and expects little rain in the north-west. Four official signals and what to measure for each, with water level at the centre.
The week's two pieces, linked by relative humidity (from the dew point to leaf wetness), three European signals with their sources, and what is coming: the European climate resilience framework expected on 20 October and the end of summer time on the 25th.
Hours of leaf wetness feed many disease warnings, yet there is no standard way to measure them. Where to put the sensor, at what angle and orientation, whether to paint it and how to set the threshold with your own observations.
