• The Colegio de Enfermería de Alicante is running a free online course on preventing domestic accidents from 24 September to 24 October, open to residents across the province.
• The Olive Press reports that AEMET has issued orange warnings for possible flash floods along the northern Alicante coast and parts of Catalonia.

Today's essentials

Heat near 35°C inland holds until rain hits Friday. Temperatures across the Costa Blanca will stay high through Wednesday 16 September, with inland Alicante province reaching around 35°C and the coast holding near 30 to 31°C, before a front brings a drop and possible showers from Friday 18 September, according to AEMET and À Punt.

AEMET's municipal forecast for Alicante and its coastline points to highs sitting steadily around 30 to 31°C from Sunday 13 to Wednesday 16 September, with overnight lows of 19 to 20°C and a 0 percent chance of rain right through Wednesday. À Punt, the Valencian broadcaster, expects highs of 30 to 35°C across most comarques of the region on Monday, edging higher on Tuesday.

Jorge Olcina, director of the University of Alicante's meteorological observatory, told COPE to expect at least six consecutive days of above-normal midday temperatures over the province: roughly 31 to 32°C on the coast, up to 35°C inland, and nights close to 20°C by the sea. COPE attributes the spell to an anticyclonic ridge pulling a warm air mass over the peninsula, with the heat building gradually from Friday 11 to Wednesday 16 September.

One nuance worth keeping in mind: the most extreme readings quoted by À Punt, 35 to 38°C on Tuesday, apply to inland comarques of Valencia and Castellón such as the Alto Millars, the Serranía and the Vall de Cofrents-Aiora, rather than the Costa Blanca itself. À Punt also flags a risk of late-afternoon storms inland from Wednesday, while AEMET still shows 0 percent rain over Alicante city that day, a gap explained by the two forecasts covering different areas.

The turn comes later in the week. AEMET puts the chance of rain over Alicante city at 15 percent on Thursday 17 September, then 50 to 65 percent on Friday 18 and 55 percent on Saturday 19, marking the end of the stable, dry heat.

What this means for you: if you have been putting off a beach day or an inland walk, the window is now through Wednesday, when the sky stays clear and highs are hot but not punishing on the coast. Keep water on you, expect warm nights near 20°C by the sea, and treat any weekend plans as provisional, because rain looks increasingly likely from Friday onwards. AEMET's rain probabilities for Alicante are worth rechecking day by day as the front approaches.

Weather today

Today on the Costa Blanca: warm and dry. Open-Meteo forecasts a warm, rain-free Sunday 13 September across the Costa Blanca, with highs of 28 to 29°C and no precipitation expected anywhere on the coast or inland.

In Alicante city, Open-Meteo gives a low of 23°C and a high of 29°C under partly cloudy skies, with no rain and a light breeze up to 14 km/h: comfortable enough for the beach or a long lunch outdoors, with a hat and water for the middle of the day.

Inland, Cocentaina sits cooler overnight at 15°C but climbs to 28°C under an overcast sky, while the southern coast around Torrevieja runs from 22 to 29°C, partly cloudy, with a slightly stronger sea breeze of up to 16 km/h. Rain probability stays at 0 percent everywhere, so it is a straightforward day out.

Transport & traffic

• Alicante airport past the 12 million mark. Alicante-Elche airport has welcomed its twelve-millionth passenger of the year, a milestone AlicanteOut reads as a sign of the Costa Blanca tourism sector's health. For anyone flying in or out, that scale of traffic is a double-edged detail: it means a wide choice of routes and frequencies year-round, but also that check-in, security and car-hire desks can back up sharply in peak periods. AlicanteOut frames the figure as evidence the region's visitor economy remains strong, so allowing extra time at the terminal on busy weekends is sensible.
• A possible new Alicante Norte rail station. TodoAlicante reports a project for a new station, Alicante Norte, that could eventually serve both AVE high-speed trains and a planned coastal line, the Tren de la Costa. The reporting is at the plan stage, without confirmed dates or costs, so it is one to watch rather than to bank on. If it goes ahead, a second major station would matter for residents in the north of the city and along the coast, potentially cutting the trek to the central station for high-speed and regional services alike.

What's changing for you

• Free online course on home-accident prevention. The Colegio de Enfermería de Alicante is offering a free online course on preventing domestic accidents from 24 September to 24 October, open to residents across the province of Alicante, according to elperiodic. Because it runs online and costs nothing, it is an easy one to sign up for if you have young children or older relatives at home. Registration opens ahead of the 24 September start, so it is worth checking the Colegio de Enfermería's channels now to secure a place before the course begins.
