12月のサマナについての旅行者の声
Regulars are specific the dry season here officially runs December through April, sunny days and lower humidity the norm along with virtually zero chance of a hurricane this late in the year. Our row backs that warm, genuinely wet read, 27.1C reading as a hot 30C, over 23.7C nights feeling 27C, with 57.3mm of rain across 16.5 days and humidity at 80 percent. Regulars are consistent early December specifically tends to bring the better weather within the month, generally nice and hot with real rain still a possibility on any given day despite the dry-season label. The sea sits at a warm 27.7C. The record: 9.9 hours of sun, a 14.2 kph wind and AQI 36.

April is the month after. The humpback season closes on the 31st of March, the whales begin heading north in the first days of April, and by the middle of the month there is effectively nothing to see - so a trip booked here for them needs to be a fortnight earlier. April is still inside the favoured December-to-April run and remains peak travel season on the island. Our row is wetter than March's, though, at 94.6mm across 15.3 precipitation days against 60.7 and 12.7, so the dry season is already loosening. Heat is up too: 27.9C over 23.5C reads as 32C and 27C, with the sea at 27.5C. The record: humidity 78 percent, 11 hours of sun, a 15.3 kph wind and AQI 39.
For once the month and the animal agree. Humpbacks come into Samana Bay to court and calve from January to March, and the season is fixed to the day: the 15th of January to the 31st of March, in what is a designated marine mammal sanctuary. Regulars add that later is better if you want to see mothers with their young, which makes March the pick of the three rather than the last resort - and that a trip in April misses it entirely. Excursions all leave from the port in Samana town. Our row is undemanding around it: 27.3C over 22.9C reading as 30C, 60.7mm across 12.7 precipitation days at under five millimetres each, and a 26.5C sea. The record: humidity 76 percent, 11 hours of sun, a 16.2 kph wind and AQI 39.
The humpback season in Samana Bay runs from 15 January to 31 March, and February into early March is its peak - mid-February is the date regulars give for the height of the migration. The weather is the variable rather than the whales: a trip at the start of one February came back with cloud, chop and everyone in soaked rain jackets, and operators cancel for weather with a re-book or a refund. Our row's 14.1 precipitation days carrying only 40.7mm is the usual Caribbean shape, frequent short showers rather than wet days. The record: 26.8C days that feel like 29C, 22.9C nights, 10.4 hours of sun and a 25.8C sea.
Samaná-area forum threads describe July as hot and sunny most days, typically 33C or more, with tropical showers a regular but usually brief feature rather than something that derails a day - warm evenings and lots of sun are the overall theme. Multiple posters specifically pushed back on online weather apps that show high rain-percentage forecasts here, calling them misleading since actual conditions run far sunnier than the numbers suggest; a passing shower can register as 'rain' for the day while barely interrupting time outside. July does fall within hurricane season, so posters recommended keeping half an eye on tropical storm tracking even on an otherwise sunny-forecast trip.
