Summer in Sydney is the harvest peak for fruiting crops, and a planting window only for the heat-tolerant, basil, late beans, succession lettuce in shade. The city sits in temperate territory, winter lows around 8°C, summer highs around 29°C, and the summer months (December, January, February) carry a recognisable rhythm that's worth knowing before you plant.
From seed in Sydney this summer: Beans, Cucumber, Zucchini, Basil, Spring Onion, Beans (climbing), Pumpkin, Sweet Corn, Dill, Beetroot, Carrot. That's a long list, which is the upside of Sydney's temperate conditions in summer, direct-sowing into raised beds gives you the best germination and the strongest root systems for the season ahead.
As seedlings in Sydney this summer: Eggplant (last chance), Capsicum, Sweet Potato, Zucchini, Eggplant, Sweet Potato slips, Watermelon seedlings, Silverbeet. Buying seedlings from a local nursery shortens the calendar by 4-8 weeks compared to seed, which matters most in Sydney's shoulder windows.
Harvesting in Sydney this summer: Tomato (first!), Zucchini, Cucumber, Beans, Garlic, Spring Onion, Lettuce (bolt-resistant), Tomato, Basil, Capsicum, Eggplant, Pumpkin (maturing). The harvest peak runs across the season's middle month, when warm-season crops planted in the previous shoulder are coming into full production.
Sydney's wet summers (November-February) bring fungal diseases, ensure beds have excellent drainage and space plants for airflow around tomatoes and zucchini. Coastal Sydney rarely frosts, so you can grow silverbeet, kale, and Asian greens year-round without frost protection. If you want the printable, see the full Sydney planting calendar.
Sydney's summer suits raised beds for the simple reason that raised beds drain faster and let you control the bed mix, both of which matter when the season's weather extremes try to either drown or bake your crops. The raised bed calculator sizes the bed; the companion planting guide fills it out.
