Quick answer
In October, choose Galle over Mirissa: it is usually the wettest month island-wide, the sea is unsettled and Mirissa's whale boats have not yet resumed. In November the balance shifts. The sea begins to calm, whale watching restarts in most years and Mirissa's restaurants reopen, so by mid to late November a split stay works again. Prices in both towns stay well below the December to March peak throughout.

October in Galle and Mirissa
October in Galle and Mirissa belongs to the second inter-monsoon. The south-west winds have faded, the north-east monsoon has not begun, and the air is still and heavy. Mornings are often fine. By early afternoon, clouds pile up and thunderstorms break with real force, sometimes flooding roads for an hour.
The sea in October is calmer than in July but unsettled, with brown water near river mouths after rain. Mirissa is still largely closed, and Galle is the practical choice. Flooding and landslides inland occasionally disrupt travel in October, so allow slack in any tight connection.
- →Mornings: usually the best part of the day.
- →Afternoons: heavy thunderstorms are common.
- →Mirissa: quiet, many businesses still shut.
- →Galle: open and uncrowded.

Which to choose, week by week

- →October: Galle.
- →1 to 15 November: Galle, with a day trip east on a fine day.
