February is a better month for this than June, because you get the place to yourselves.
The afternoon
An empty beach. All of them are empty in February, and the light is hard and clean. Walk the shoreline from Baiter to Hamworthy instead if the wind is up: flat the whole way, water beside you.
Sunset, early
The harbour faces broadly west and the sun goes down it at around half past four in mid-February, which means you can watch a full sunset and still have the whole evening. Baiter and the Hamworthy shore are the spots. See Poole’s light.
Dinner
The small rooms behind the Quay in the Old Town, or Ashley Cross for more choice in a short walk. Book ahead: February is quiet in Poole except on this one night. See restaurants.
Or make it a weekend
Prices are at their lowest of the year, and a spa afternoon on the peninsula costs considerably less in February than in August. See accommodation and health and wellbeing.
