The south-west monsoon is at full strength in July, so the offshore holds through most of the day rather than just the morning, and the swell out of the Indian Ocean is as steady as it gets. The Main Point at Arugam Bay runs long and workable, and it has the crowd its reputation earns it.
The figures say something about this coast that is worth knowing before you compare it with January. The east loses its days to swell that is too small and almost never to wind: at Peanut Farm, in the heart of the season, six days in a hundred are blown out. On the south coast it is the reverse, with about a quarter of the days at Weligama going to wind. Two coasts on one island, two opposite problems, and the practical consequence is that the forecast you read here is a height and the one you read in January is a direction.
Five coasts are at their own peak in July and Costa Rica is warmer at 29°C, but Sri Lanka has the best beginner rating of the five. The others are Nicaragua, Mozambique and South Africa, and none of them is a coast you would choose for a first week. That is a narrow distinction and it is a real one: July is a month when most of the world at its best is at its best for experienced surfers.
A week here is a week of driving a short coast rather than surfing one wave, and July is when that matters most. Whiskey Point, Peanut Farm and Elephant Rock spread the same swell over twelve kilometres and take the pressure off the Main Point. The other thing July brings is the town at capacity, a main street of bars full of surfers from everywhere, and not many beds in it. Book early or take September.
