Due to its coastal setting, Portsmouth manages to avoid the worst of the northerly winds, being protected by the Portsdown Hill, and this is certainly reflected in its higher-than-average monthly temperatures. From late spring until the early part of autumn, Portsmouth boasts an enviable climate, with warm weather and crowds of tourists.
