Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.

Weather read at the town, by the harbour: ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

April: quiet. Busiest from June to September; quietest from October to April.

What to pack

  • A proper coat, hat and gloves: nights average -1°C.
  • A packable rain jacket for the 9 or so rainy days.
  • Sun protection: about 9 hours of sunshine a day.
  • Humidity averages 80%; breathable fabrics dry faster.

Each line is a threshold over the ten-year figures above, not advice from anywhere else.
