Pogoda Tossa de Mar (Costa Brava) — wrzesień

September in Girona is warm by day, cooler in the evening and, by late in the month, close to ideal - mid-20s with far less rain than the summer, which our row puts at 28.1C over 13.5C with 6 precipitation days. The point regulars make that no climate row could is about the city rather than the sky: Girona is inland, so it half closes through August while everyone is at the coast, and comes back to life in September with the bars and restaurants open and busy again. That makes it the most sociable month of the year here, and it arrives just as the summer visitors leave. The record: feels-like 30C, 70.1mm of rain, humidity 75 percent, 10.2 hours of sun and AQI 37.

Tossa de Mar's forum pushes back on the idea that Costa Brava winters are dreary: several posters describe January as chilly but typically sunny with clear blue skies, closer to a crisp day than the grey damp of a UK winter, which matches the destination's own mild low-teens-C average high. Most tourist-facing bars and restaurants close for the season in October, so the town reverts to serving its Catalan residents rather than visitors - it's quiet, but not shut down, and weekend day-trippers still fill the seafront spots when the weather cooperates.

Forum posters describe July as when the Costa Brava season really comes together - sea temperatures around 23C and genuinely comfortable for swimming, with the town noticeably livelier and warmer than earlier in summer. Posters note Tossa stays relatively calm midweek in early July, but by mid-month crowds build and stay heavy through the end of August, so early-to-mid-July offers a window with somewhat thinner crowds while conditions are already excellent. Heat and humidity are genuinely present by mid-July, and nights stay warm enough that even an after-8pm walk still feels balmy rather than cool - a real contrast to the shoulder-season evenings earlier in the year.
