## Return to Warm Weather Expected

From Monday 24 August, conditions will stabilise. Rainfall probability drops sharply, skies are expected to clear, and temperatures may rise again, nearing 30°C by midweek. Currently, AEMET lists no weather warnings for the Barcelona coastal area despite ongoing humidity. Before the shift, Tuesday 18 August saw a maximum temperature of 33°C, with a 'feels like' temperature of 37°C due to high humidity. Minimums hovered around 27°C, under overcast morning skies that cleared to partly cloudy by late afternoon.
