There is a fortnight in November where you can watch it happen. The rain stops being a daily event, the humidity drops, and the streets get louder.
What changes in a class
Size, and then everything downstream of size.
A busy room has less floor space, which affects how much you can spread out, and less individual attention, which affects how much correction comes your way. Neither is a complaint. A full room has an energy a quiet one cannot manufacture, and plenty of people practise better in it.
But if you have spent the low season getting used to a teacher having time to come and adjust you twice a class, November is an adjustment.
What to do about it
Come earlier. Not to the class, to the day. Morning classes fill later than evening ones and the room is calmer at both ends.
Message me rather than turn up hopeful. You will get an answer about the actual class from somebody who knows what is in it, which is more than a screen can tell you.
If the class you wanted is full, ask me what else is on. My timetable is wider than most people realise, and half the point of running yoga, Pilates, dance and Qigong under one roof is that the alternative to your first choice is never nothing.
For people who live here
You already know. Your habits change for four months and you get them back in April.
The thing I will say: the visitors in the room are not the problem, and being the local who resents them is a bad way to spend a season. Some of them are here for the third year running and will be practising beside you long after this particular November.
For people visiting
You have arrived in the good weather. Everybody had the same idea. Plan slightly further ahead than you would in September and the season is excellent.
