In general, the most optimal for visiting Jamaica is the time from November to March, because the temperature is comfortable, on average about +27 degrees, and rain is extremely rare. This period is optimal and for traveling with children. However, during this period there is a huge number of Americans and Canadians, which makes prices for a huge number of services and excursions extremely high. Jamaica for residents of the United States and Canada, this is something like Turkey or Egypt for us, and since they have more income, then they spend without thinking, more money.
But by and large, this "high" season can be called such quite with a large stretch, because the island is in the tropics and there is always hot and always wet. So you can relax here all year round without special discomfort. The average annual daytime temperatures fluctuate in the range from +23 to +36, while water does not fall below 24 degrees. Although ... even if it is rare, but in January-February, it happens that the temperature at night is lowered below 20 degrees, but will you scare this temperature?
There is on the island and such a concept as the rainy season. But again, this is also a convention, then as rains if they go, mostly at night, which does not interfere. And if there are afternoon, they are short-term and maximum than they can spoil life, so it is an increased humidity that the northeast Breeze that blows is perfectly correcting here.
But that's what really can spoil the vacation, so these are tropical hurricanes that are characteristic of this region. The high probability of their occurrence occurs in the period from July to November.
And otherwise, everything is fine!
