Panama is protected from hurricanes and storms because of its geographical position and therefore the charters are available year-round. However, 2 seasons prevail:
High Season from December to April: it is the season of the trade winds (North / East wind), which means regular winds and little or no rain. Visibility under water is not the best and there is some current: It is the ideal season for truly sailing enthusiasts!
The rest of the year, winds are milder and there are scattered showers (nothing too dramatic): the visibility under water is much better with the possibility of exploring the “outside” of the reefs, there is more light and sunset is sometimes spectacular: it is the best season for coral reef exploration and marine fauna discovering. There are more solitaire anchorages because it is low season.
Temperatures vary a little depending on the seasons: the average daytime temperature ranges are from 27 ° C a 35 ° C (82 ° F a 95 ° F) and average sea temperature goes from 25 ° C a 27 ° C (77 ° F a 82 ° F)..
No vaccination is really necessary for Panama City or the area of San Blas. However, please consult the correspondent authorities before leaving your country.
