If you're planning trail runs or beach days in Barcelona, timing is everything. I did the Carretera de les Aigües route in May and conditions were flawless — 21°C, 12km/h breeze, UV at 6. July-August pushes UV to 9+, which is brutal between noon and 4pm; shift activities to early morning. Sea temperature hits 26°C in August, perfect for swims. The wind picks up reliably afternoons year-round, helping with heat but making paddleboarding tricky. October is the unsung hero for hiking — cool, golden light, empty paths.
