The September week when heads of state fill Turtle Bay for the General Assembly's general debate and the rest of Manhattan schedules itself around them.
Une page d'événement vous indique quand il a lieu (avec le niveau de certitude sur la date), pourquoi il est important, quelle est l'atmosphère de la semaine qui l'entoure, quand arriver et repartir, où les participants séjournent, comment l'accès fonctionne, et quels événements le précèdent et le suivent sur le circuit.
High-level week is the annual opening of the United Nations General Assembly's general debate, when the heads of state and government of the member states address the Assembly in turn from the podium in Turtle Bay. The formal business is the debate and the summits scheduled around it; the practical consequence is that most of the world's governments, and the diplomatic, philanthropic, financial and press apparatus that follows them, are in one square mile of Manhattan for seven days.
What has grown around that core is now larger than it. Climate Week NYC, run since 2009 by the non-profit Climate Group, occupies the same days — 20 to 27 September in 2026 — and its organisers describe more than 100,000 people at several hundred events across the city. Foundations, development banks, universities and corporations schedule their own summits into the week, and Midtown ballrooms are booked out for them.
01Pourquoi c'est important
No other week concentrates this many governments in one city, and the consequence is that a great deal of business with nothing to do with the United Nations is scheduled to catch people who are already there.
02La semaine environnante
Midtown East becomes difficult and stays that way. The police impose frozen zones around the headquarters and the delegation hotels, First and Second Avenues and stretches of the FDR Drive close repeatedly for motorcades, and crossing the East Fifties on foot is often faster than any vehicle.
03Quand arriver
Arrive Sunday and be in place before Monday morning, when the first summits convene and the road closures begin.
04Où séjourner
Delegations take the Midtown East hotels around the United Nations and along Park and Lexington; those blocks are inside the security perimeter, which means secure but slow.
05Accès et hospitalité
The General Assembly Hall is closed to the public during high-level week; access is limited to accredited delegations, mission personnel, accredited non-governmental organisations and credentialed press, and headquarters tours are suspended. The general debate is broadcast free on UN Web TV and archived.
06Où se déroule l'activité sociale
The visible week happens in Midtown hotel ballrooms, in the Ford Foundation and Asia Society auditoriums, in university halls at NYU and Columbia, and in the lobbies of the hotels where delegations are billeted.

09Historique
The General Assembly first met in London in January 1946 and moved to New York the following year, settling into the Turtle Bay headquarters when it opened in 1952. The surrounding week grew from the 1990s as the Assembly began scheduling summits alongside the debate, and accelerated after the 2015 adoption of the Sustainable Development Goals and the Paris Agreement.
10Qui s'y trouve
Heads of state and government and their delegations; foreign ministers and permanent representatives; UN agency and multilateral bank leadership; foundation and non-governmental organisation heads; development-finance and impact investors; corporate sustainability teams; climate scientists and campaigners; and several thousand accredited journalists.

| 2027 · 82nd session high-level week | · 82nd session high-level week | PrévuNot yet published. Under the Assembly's rules the 82nd session will open on Tuesday 14 September 2027, and in the years when the session has opened that late — 2021 and 2022 — the general debate began the following Tuesday. The estimate therefore places high-level week on 21-27 September 2027; if the two-week interval used from 2023 to 2026 is applied instead, it would begin on 28 September. |
