High and low tides at Saint-Jean Bay: now, the next 7 days, the last 30 days and month by month, in St Barth local time.
Tides in St Barth are subtle: the difference between high and low water (the tidal range) is usually only a few tens of centimetres. The regime is mixed, mainly diurnal: depending on the day, the sea rises and falls once or twice, with high tides of unequal height.
A small range still matters on a shallow spot like Saint-Jean Bay: a few centimetres more or less change the water depth over the reef and the way waves break on it.
Either way, wind and swell matter far more than the tide at Saint-Jean: check them live on the dashboard before heading out.

Yes, despite the small range: at low tide, the wave breaks over shallower water above the reef; at high tide, there is more water above the coral heads to swim without touching them.
