Tikorangi is technically in a temperate zone although its mild conditions mean that many subtropical plants can be grown successfully outdoors in the garden, including citrus all year round, avocados, sapotes and many tender ornamentals such as vireya rhododendrons. The banana palms need to be covered in winter in order to crop, but the rest of the plant material takes care of itself.
Summers are relatively cool with daytime average of around 24 degrees Celsius. Winters are mild with a daytime average around 14 degrees Celsius. Being within five kilometres of the coast, there is not great variation between day and night temperatures. The disturbed westerly air pattern keeps air moving and stops any temperature extremes.
The few frosts are usually minor – a degree or two of ground frost at the most.
Sunshine hours are high, around 2500 hours. On average, 150cm of annual rainfall is pretty evenly distributed throughout the year. Serious droughts are unheard of – 3 weeks without rain and we start talking of drought. The garden is never watered and does not need an irrigation system.
The area has friable and fertile volcanic soil, the legacy of the volcanic Mount Taranaki about 50 kilometres away.
