Climate
- A wholly maritime climate prevails, with south-easterly winds blowing directly from the Southern Ocean and prevalent during the growing season, especially from December to March.
- The average summer temperature is 25°C (77°F), significantly cooler than that of Adelaide. The low growing season rainfall makes a small amount of irrigation desirable.
- High relative humidity of 64% means that the vineyards are susceptible to powdery mildew and Botrytis. Overall though, the climate is temperate and devoid of extremes, with a particularly even accumulation of heat.
Soil
- Soils vary greatly from acid duplex to alkaline sands, loams and clays overlaying limestone.
- Some soils are similar to those of Padthaway and can sustain good yields if adequate water is supplied.
