when do shamrock shakes come out

Shamrock Shakes at McDonald’s typically come out in mid‑February in the U.S. and run through St. Patrick’s Day in March at participating locations.

Quick Scoop

• In recent years, U.S. locations have launched Shamrock Shakes around early to mid‑February (for example, February 10 in 2025 and similar mid‑February dates before that).

• The promo usually runs until shortly after St. Patrick’s Day in March, but exact end dates can vary by restaurant and region.

• McDonald’s describes the shake as a limited‑time seasonal item that “magically appears once a year, usually in March, and only for a limited time” at participating restaurants.

2026 timing (what’s being talked about)

Recent coverage for 2026 reports that Shamrock Shake “season” is set to start on February 17 in the U.S., slightly earlier than some previous years, though corporate hasn’t widely publicized the date yet. Individual restaurants sometimes put them on sale a bit early or late, so local timing can differ.

How long they stick around

• Generally available: mid‑February through mid‑March, sometimes disappearing right after St. Patrick’s Day.

• Availability can end sooner if a location sells out or later if they still have promo supplies.
