The short answer
If you want one recommendation: March and April. It is still properly warm, the summer wind has dropped off, the wine harvest is happening, the sea is at its warmest of the year and the December crowds have gone home. Most locals will tell you the same thing.
October is the other strong answer — whales still in the bays, everything green, long days, and prices well below midsummer.
What follows is the honest version of each season, including the parts the brochures leave out.
Summer — December to February
Hot, bright, busy and windy
Long dry days, temperatures usually in the high twenties, and the beaches at their best. It is also the busiest and most expensive time of the year: mid December to mid January the city is completely full, and popular restaurants and tours need booking weeks ahead.
The real catch is the wind. The south-easter — the Cape Doctor — blows hardest in these months and regularly shuts the Table Mountain cableway for the day. If you come in summer, treat the mountain as an opportunistic outing rather than a fixed plan.
Autumn — March to May
The locals' choice
Warm days without the ferocious wind, the sea still warm from summer, the light turning gold, and the Winelands in the middle of harvest. The crowds thin out sharply after January and prices follow.
May starts to bring the first proper rain, but it arrives in bands rather than all day, and the mountain is green again by the end of it. If you can only come once, come now.
Winter — June to August
Green, dramatic and cheap
This is the wet season: cold fronts roll in off the Atlantic, the mountain disappears into cloud and then reappears with waterfalls down its face. Daytime temperatures sit around the mid teens. It rains, but rarely all day and rarely all week.
What you get in exchange is a city with nobody in it, the lowest prices of the year, easy restaurant bookings, spectacular storm-watching, and the first southern right whales arriving from July. From late August the West Coast starts to flower.
Spring — September to November
Whales, flowers and everything waking up
Arguably the most interesting season to be here. The wildflowers on the West Coast peak in late August and September — how good they are depends entirely on the winter rain. The whales in Walker Bay are at their best in September and October, close enough to Hermanus to watch from the cliff path without a boat.
The weather is unsettled and can give you all four seasons in a day, but it warms steadily, the days lengthen and the crowds have not arrived yet.

Questions people ask
What is the single best month?
March, if you want warmth and calm. October, if you want whales and green. Both beat December on every measure except sea temperature and party atmosphere.
Will it rain on our holiday?
Between November and March, almost certainly not. Between June and August, some days yes — but Cape Town rain tends to come through in fronts, so you get clear spells between them.
Is it worth coming in winter?
Yes, if you want the Cape rather than a beach holiday. Green mountains, dramatic seas, whales arriving, no queues and much lower prices.
When should we avoid?
Nothing needs avoiding, but mid December to mid January is expensive, crowded and windy. If you have a choice, shift a few weeks either side.
How far ahead should we book a guide?
For December and January, months ahead. For the whale and flower seasons, as early as you can. The rest of the year a few weeks is usually fine.
