The best Months to dive in Grevelingen

Grevelingen offers year-round diving opportunities, with conditions varying seasonally. Water temperatures range from 5°C–18°C/41°F–64°F throughout the year, with the coldest months from December to February. During summer, the warmer temperatures from June to September provide more pleasant conditions for divers.

Visibility is generally good, ranging from 3 to 10 meters/10 to 33 feet, but can be affected by weather conditions such as wind and currents. Strong winds, particularly in autumn and winter, may reduce visibility and create challenging diving conditions. While diving is possible year-round, it's advisable to plan trips during spring and summer for optimal conditions.

Dive Sites

One2Dive, 4907 ZK Oosterhout

Kerkweg, Den Osse (★3.9)

Dive site Kerkweg in Den Osse is one of the most famous dive sites in Zeeland. Here you can dive from the jetty on oyster beds, an artificial reef of reefballs and many other hard substrate that is nicely overgrown. The maximum depth is about 30 metres, but you will find most life in the shallow water.
Scuba World Arnhem, 6811 CG Arnhem

Scharendijke “Kabbelaar“ (★3.7)

You reach the dive site via a jetty. You can dive into the water and along the wall. You will find a platform and after a short swim also an artificial reef consisting of reefball, ideal to dive back towards the dike.
One2Dive, 4907 ZK Oosterhout

Dreischor Frans Kokrif (★3.9)

Just before Dreischor Gemaal is another dive site. This is enhanced by the artificial reef that was built here a few years ago. Just like at Scharendijke and Den Osse, a ribbon of reef balls have been laid here. Parking is easy and via a staircase, over the dike, you come to a riser where you can go to the water.
One2Dive, 4907 ZK Oosterhout

Den Osse Haven (★3.9)

It is a 200 meter walk along the dike. Mean the left side of the breakwater otherwise you will end up in the harbor right away! The first part from the shore is quite shallow and sandy. At about 100m from the shore the bottom then goes steeply down (especially near the breakwater).
Yoeri D. (#3526102)

Stoofpolder “Het Licht“ (★3.3)

This spot is nicknamed the Light, after the harbor light that is here. It is a beautiful reef and due to its location at the end of the Oosterschelde the current is minimal. Be careful! Too far to the southwest and you end up in the shipping channel.
One2Dive, 4907 ZK Oosterhout

De Muur (★3.9)

The dive site is located around the four breakwaters with the characteristic beaches in between. You can enter the water from the beaches and dive out to the ends of the breakwaters around 5 meters deep, which are beautifully overgrown. The bottom slopes down to about 15 meters. Limited parking spaces.
One2Dive, 4907 ZK Oosterhout

Dreischor Gemaal (★3.8)

This dive site is not subject to tides, so you can dive here all day long. From the stairs, you can dive both to the left and to the right. On the right is the pumping station, which is very nicely overgrown and sometimes produces attractive images for macro photographers.
One2Dive, 4907 ZK Oosterhout

Dolfijntje (★3.5)

Het Dolfijntje dankt zijn naam aan het voormalig drijvende restaurant en bijbehorende bak waarin een kijkje in de onderwaterwereld zichtbaar was. Het restaurant sloot in 2007 en is sinds de brand van 2009 verwijderd.
One2Dive, 4907 ZK Oosterhout

Blokkendam Noordzee zijde (★3.0)

One of the few interesting dive sites on the North Sea side in this area. Be careful, you are not allowed to dive in the harbour and in calm weather it is nice to dive the outside of the block dam. Also take a trip on the sand and go looking for sepiola and flatfish.
One2Dive, 4907 ZK Oosterhout

Zijpe (★3.3)

Diving between the hanging culture is a real must do! As a photographer this provides, especially on sunny days, a great spectacle! Please note, you are not allowed to dive freely here and you need permission.
One2Dive, 4907 ZK Oosterhout

Ankerplaats (★3.0)

The anchorage is located close to Bruinisse. A fairly shallow spot, nice as a first dive for beginners or other specific purpose. In the summer also used a lot as a swimming place for the locals.
One2Dive, 4907 ZK Oosterhout

Loswal (★3.6)

You enter the water on the small sandy beach. Loswal is a shallow dive site, max. 15 meters, and you have to swim out quite far to reach some depth. It is therefore an ideal place for beginning divers or to do training.
One2Dive, 4907 ZK Oosterhout

Bommenede (★3.7)

The great added value of this spot is that you can easily park on the outside of the dike, so you don’t have to walk over it! Furthermore, the spot is quite shallow and you quickly dive towards the channel where diving is prohibited.
One2Dive, 4907 ZK Oosterhout

Bommenede Polder (★3.3)

The spot is practically only accessible by boat. The remains of the village are little more than a pile of overgrown rubble. It may be worth diving here, but in the summer the location can be dangerous. The shipping channel and the busy pleasure boating pose a risk.
One2Dive, 4907 ZK Oosterhout

Kijkuit Polder (★3.7)

Kijkuit is shallow. The bottom consists of silt and swirls up quite easily. You can enter the water at various places, between the breakwaters it is very shallow. You can also enter the water at the end of the breakwater at the head of the dike, but watch the shipping channel.
