U/Th constrained growth of Bermuda speleothems is analysed to reconstruct past sea level.
- class="label">•
Local relative sea level was at or above 1.5 m during the MIS5e, c and a highstands.
- class="label">•
A double highstand peak above 1.5 m is suggested during MIS5a.

New constraints on the timing and maximum duration of MIS5 highstands are provided.

These data can be used to constrain glacial isostatic adjustment models in the forebulge area.
