Highland "winter" in Jalisco — the rains have stopped, so do I reduce and insulate at all or is that a northern habit?

Jalisco, ten years, eighteen colonies at about 1,600 m. Half of what I read on this forum is about a winter I don't have, and I'd like to work out which parts still apply to me, partly for myself and partly because I mentor two new beekeepers who are reading northern advice and getting confused. Our pattern: the rains have just finished, nights are dropping to 8-10°C and days are 24-26°C and sunny. There's a dry season flow coming from late November, and in between there's a real dearth for a few weeks. Colonies keep brood going all year, just less of it. What I want to know from anyone in a similar climate — highland Mexico, Kenya, southern Spain, anywhere with a dry cool season instead of a frozen one — is whether cool nights plus warm days needs any insulation at all, and whether the dearth or the cold is the thing to prepare for. And is continuous brood the reason our mite management never feels finished?
