The news from Costa Rica today is "Cold Spell for the next 2 Days"
Just what is "cold" anyway? For folks in San José, cold = a high of 22 degrees Celsius (71.6 F)
Consider that "normal" highs for late October (the rainiest and coldest month) are 26-28 C (79 - 82.5 F).
I remember our homestay hostess in Sámara saying that San José was coooold - she showed us a sheepskin jacket she had just for SJ trips. This was told to us in February, in the middle of a 90+ F day...
