Climate overview
Temperature
Monthly mean temperatures reach their lowest point in January, at 24.5 °C, and their highest in both July / August, at 27.7 °C. This suggests a fairly limited spread in the monthly averages, but these figures are not daytime maximums and cannot show how much temperatures vary from one day to another. Across the calendar-month means, the unweighted mean is 26.2 °C. It is a useful broad summary, not a day-weighted annual average or a description of temperatures at a particular hour.
Rain
Mean daily rainfall is lowest in February, at 0.74 mm/day, making it the clearest option in these data for visitors prioritising lower average rainfall. The highest monthly mean is in November, at 4.01 mm/day. These are daily averages, not monthly totals; neither value tells you how often rain falls or guarantees dry weather in the lower-rainfall month. The unweighted mean of the monthly daily-rainfall averages is 2.17 mm/day. Treat it as a summary across the calendar months, rather than a prediction for a specific visit.
Sunshine
Mean daily sunshine duration is highest in June, at 11.70 hours/day, and lowest in November, at 9.67 hours/day. These figures can help with broad outdoor-planning comparisons, but sunshine duration is not the same as day length and does not guarantee clear skies on any given day. The unweighted mean across the monthly sunshine averages is 10.69 hours/day per day. It summarises the calendar-month figures without indicating the conditions on a particular date.
Best Travel Time Guide for La Romana, Dominican Republic: Ideal Seasons and Weather Insights
For a visit planned around cooler monthly mean conditions, January is the relevant point of comparison, with a mean of 24.5 °C; this is not a daytime maximum, so it cannot describe the full range visitors may experience during the day. If lower average rainfall is the priority, February has the lowest mean daily rainfall, 0.74 mm/day. That average does not promise rain-free days or show how frequently rain occurs, so practical rain preparation remains sensible. Visitors prioritising more average daily sunshine can look to June, at 11.70 hours/day, while November records the lowest mean, 9.67 hours/day. Sunshine duration is not a measure of daylight length or a forecast of cloud cover. For rain preparation, note that November has the highest mean daily rainfall, 4.01 mm/day; this is an average, not a monthly total or a guarantee about conditions during a particular trip.
