January is Poole stripped back to what it actually is, and there is a lot to be said for it.
The birds
This is the harbour’s real season. Poole Harbour is a RAMSAR wetland and the mudflats hold waders and wildfowl in tens of thousands. Upton Country Park and Holes Bay are the accessible places to watch from. Free. See wildlife.
The water
Cold-water swimming has a committed following here, and groups swim right through winter. If you join them: go with others, acclimatise slowly, get warm quickly afterwards, and know the tide. There are no lifeguards in January. See beach safety.
The walking
Empty beaches, hard winter light and the harbour shoreline from Baiter to Hamworthy, flat the whole way. See winter walks.
Indoors
Poole Museum is free. Lighthouse programmes through the winter. The Old Town pubs are what January is for.
The prices
The lowest of the year, by a distance. See Poole in winter.
