Why is Pendrell Sound the warmest water on the coast?
Pendrell Sound holds the warmest salt water on the coast — dependably 20°C+, often 24–25°C — and a coast-wide oyster nursery, so boats enter slow and no-discharge, tying stern-to-shore in a deep fjord.
Quick facts
- Where
- East Redonda Island, off Waddington Channel; the head marks the official northern limit of the Salish Sea
- Water
- The "warmest saltwater north of Mexico" — dependably 20°C+, often 24–25°C
- Rules
- Oyster-spat reserve — no-wake custom and sewage-discharge ban (tanks sealed); never touch spat floats or lease pens
- Anchoring
- Mid-sound unanchorable; stern-tie to shore at the head or the west-side nook behind the islet
- Services
- None
Pendrell is the warm ending: a fjord that nearly cuts East Redonda in two, water you float in rather than brave, and an industry so delicate the whole sound tiptoes. Come in slow, tie to the trees, and let the last days be about nothing at all. Strings of shells hang from floats collecting spat for growers everywhere — which is why boats slow to no-wake on entry and keep holding tanks sealed.
Anchoring in deep water
Mid-sound is unanchorable; favourites are the head of the sound (stern-tie to trees, gentler near-shore depths) or the west-side nook behind the islet about three-quarters up, where ten-plus boats stern-tie by the lagoon outfall. Deep sets favour a long rope rode, beam breezes shift you (twin stern ties hold you centred), and the oyster-crusted rocks are razor-sharp — wear good shoes and gloves, and watch your stern line for chafe at low tide. Captain's judgment is final. Beyond the swimming and paddling, a dinghy visit to an oyster farm (from outside the pens) buys you good spat lore; the wild slopes above are the East Redonda Ecological Reserve.

Common questions
How warm is it, really?
Dependably above 20°C in summer, often 24–25°C — you float in it rather than brave it.
Why all the rules?
The warm water powers a coast-wide oyster nursery; the no-wake custom and discharge ban protect the spat. They're rules, not politeness.
