Monthly mean temperatures stay within a relatively narrow range in the supplied figures, with the coolest monthly means at January / February reaching 21.6 °C and the warmest at July reaching 25.0 °C.

Climate overview
Temperature
The monthly mean temperature is lowest in January / February, at 21.6 °C, and reaches its highest monthly mean in July, at 25.0 °C. Across the calendar-month means, the unweighted mean is 23.2 °C. These figures describe average temperatures for whole months, not typical daytime highs or the range visitors may experience from day to day, so they are best used as broad context rather than a precise clothing forecast.
Rain
Mean daily rainfall is lowest in January, at 1.06 mm/day, while the highest monthly mean occurs in October, at 5.14 mm/day. The unweighted mean across calendar-month means is 2.88 mm/day. These are daily average amounts, not monthly totals; the lower figure does not guarantee rain-free days or indicate how frequently rain falls, and the higher figure is a useful prompt to allow for wet weather rather than a forecast for every day.
Sunshine
Mean daily sunshine duration is highest in July, at 11.62 hours/day, and lowest in November, at 9.40 hours/day. The unweighted mean across calendar-month means is 10.59 hours/day. These averages can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length and does not ensure clear skies on a particular date.
Best Travel Time Guide for Jamaica, Jamaica: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, January / February is the relevant option in the supplied temperature figures, with a monthly mean of 21.6 °C. Treat that as a broad comparison, not a prediction of daytime highs or a guarantee that every day will feel the same; flexible clothing is more useful than planning around the monthly mean alone. If lower average rainfall is your priority, January is the conditional option, with mean daily rainfall of 1.06 mm/day. By contrast, prepare for the possibility of wetter conditions in October, whose mean daily rainfall is 5.14 mm/day; neither average specifies rain frequency or guarantees the weather on your travel dates. For outdoor plans shaped by typical sunshine duration, July has the highest monthly mean at 11.62 hours/day, while November has the lowest at 9.40 hours/day. These can inform daylight activity planning, but sunshine hours are not day length and cannot promise clear conditions, so keep plans adaptable.
