October is the inter-monsoon and the weak spot in the Sri Lankan calendar. The south-west monsoon has finished, so the east coast has lost the wind that made it work, and the north-east monsoon has not arrived, so the south coast has not gained one. Rain falls on both. Sri Lanka in October rates fair, its worst month of the twelve.
The rest of the world is doing the opposite. October is the fullest month of the global calendar, with eight coasts at their own peak, more than any other month of the year: Senegal at 29°C, France at 19, Spain at 19, Portugal at 18, Wales at 15, Ireland at 13, Iceland at 9, and Mexico. If your dates are fixed and your destination is not, October is the month to let the destination move. Senegal is the warm answer and the Atlantic coast of Europe is the near one.
If October is fixed and Sri Lanka is too, take the second half of the month and take the south coast, because November is what it is turning into. Hiriketiya is the village that makes the most sense here: the cove is a three-hundred-metre horseshoe with a headland at each end, you can see the whole of it from the road, and those two headlands bend swell into a rideable shape on days when the open beaches are in pieces. It is the one address on this coast that hedges.
The compensation is real. October is the cheapest month of the Sri Lankan year, nothing is booked out, and the southern villages are reopening rather than full. That is the trade: the least dependable surf of the twelve, at the lowest prices, on a coast that is about to switch back on.
