October is the month both halves of the country work at once. The southern swell is still reaching Oaxaca as its season closes, and the Nayarit coast has arrived at its best month of the year: Punta Sayulita and San Pancho both return nineteen clean days out of thirty in October, the highest figures on either Mexican coast.
That the two north-coast breaks report identical numbers is not a coincidence and not a claim about the waves. They are ten minutes apart and read one cell of a forecast grid. What the figure describes is the stretch of coast, and the stretch of coast in October is as good as it gets.
For anybody choosing between the two Mexicos, October removes the decision and replaces it with a different one: the rains are ending, the crowds have not arrived, and the two coasts are nine hundred kilometres and a two-hour flight apart. Doing both in one trip is a real option this month and a bad idea in any other.
