Information about the Grand Mere Surf forecast

The above surf forecast table for Grand Mere provides essential information for determining whether the surfing conditions will be good over the next 12 days. A general guide to surfing at Grand Mere can be found by selecting the local surf guide option on the grey menu. Our Grand Mere surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Grand Mere) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Grand Mere may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Are you planning a holiday in Saint Barthélemy? If you are looking for accommodation near Grand Mere, camping, hotels and holiday cottages in Saint Barthélemy, consider staying in Gustavia which is 4 km (2 miles) away. Other places in and around Saint Barthélemy where you can find information about places to rent, and car hire include Philipsburg which is 33 km (20 miles) away, Marigot, The Valley and Basseterre.

We hope you find the new 12-day forecasts and additional details useful.

Kudos to everyone who helped us debug this over the past 3 months.

Be sure to click on the Advanced Surf option to see extra details about the sea-state. Look out for crossing swells and short period local wind swells and chop that will often spoil a groundswell even if the wind is perfect. As yet there is no allowance for this in the swell rating. This is something we are working on.
