The Ivory Club year has its own rhythm. It begins, unofficially, on the first evening warm enough to carry a drink up to the roof, and it ends somewhere between the last festive dinner of December and the quiet week that follows. In between sit tastings, speaker suppers, long summer lunches and a handful of dates that are gone before most members have thought about their diaries.

Knowing which seasons fill fastest — and how far ahead to plan — is the difference between hearing about a good evening afterwards and being in the room for it. Here is the year, season by season, with the booking notes that matter for each.

Spring: The Roof Reopens

Spring is the club's gentlest stretch. As the evenings lengthen, the terrace comes back into use, usually with a relaxed opening evening for members before the main diary begins in earnest. Expect aperitivo-style drinks, the first outdoor tastings of the year, and a run of suppers that sit comfortably on a weeknight.

It is also the last point in the year when you can decide on Tuesday to come in on Thursday and be reasonably confident of a table. Use that freedom while it lasts. If there is a spring dinner you have your eye on, book it as soon as the diary opens — the second half of May is busier than its mild reputation suggests.

Summer: Peak Season, Peak Demand

June, July and August are what most people picture when they think of Ivory Club: drinks on the roof at golden hour, tables that run late, and guests who arrive for one drink and stay for three. The tennis fortnight and the long evenings around it draw the largest crowds of the year, and Fridays in particular disappear quickly.

Bringing guests

Summer is the season members most want to share, so plan the guest side early. Add names when you book rather than on the day, keep an eye on how many guests your membership allows, and give the team a little notice if you are bringing a group of four or more. It is also worth having the dress conversation in advance: the roof is relaxed, the dining room is not.

A word on British weather

The roof is built for the shoulder months as much as for high summer, but nobody in London should plan an evening around a forecast. If a date matters — a birthday, a first visit from a friend — book the dining room and treat the terrace as a bonus rather than the other way round.

Autumn: Indoors, and the Serious Season

September brings the club back inside. The diary thickens with wine tastings, spirit flights, speaker suppers and the first of the year's formal dinners. This is the season for members who like a reason to be somewhere at eight o'clock, and it is where the calendar rewards a little forward thinking.

Autumn events are published in August, and the best-attended dates begin to fill before the summer holidays are over. Open the diary in the last week of August, choose two dates, and put them in your phone. Anything you book after that is a bonus.

Winter: Festive Dinners and the Close of the Year

From mid-November the club turns towards the end of the year: festive dinners, a carol evening, longer menus and a warmer, more celebratory mood all round. New Year's Eve is the single most requested night of the twelve months and is usually full well before December arrives.

Two practical steps see you through it. First, book early — earlier than feels reasonable, particularly for tables of six or more. Second, confirm the details that matter: guest names, dietary requirements and any seating preferences, all of which the team needs before the week of the event rather than on the night. If you are planning a larger celebration, speak to the events team directly, as bigger bookings are handled outside the standard diary.

Booking Habits That Work All Year

• Check the diary monthly. Five minutes at the start of each month catches most of what you will want to attend.
• Choose the shoulder. Tuesday and Wednesday evenings are quieter, easier to book and often better for a proper conversation.
• Name your guests when you book. It speeds up arrival, and for ticketed evenings it is a requirement rather than a preference.
• Flag dietary requirements early. The kitchen can accommodate most things with notice; the night itself is harder.
• Use the waiting list properly. Cancellations do happen, and members who respond quickly to a released table are usually the ones who get it.
• Update your numbers. If plans change, tell the team as soon as you know. It is the simplest way to keep your booking history in good order.

Planning Your Year

A season-by-season approach beats a scattergun one. Pick one anchor event for each part of the year — a spring supper on the roof, a summer evening with guests, an autumn tasting, a festive dinner in December — and let the rest of the calendar fill in around them. Keep your contact details and preferences current with the membership team so invitations reach you first, and remember that the busiest nights are usually the best ones for a reason. Book early, plan for the weather, and the year largely looks after itself.
