Still probably on the imprecise edge of rainy season there in Almirante. When it stops raining a lot every day then its over...hard to predict precisely when that will be, but should be soon.
Aside from wet and dry season, the meaderings of the ITCZ/monsoon trough are the biggest influence on weather in Panama. NOAA Radio
FAX (AKA "weather fax") charts
are a good reference for current and short term forecast
of ITCZ position. See "Surface Charts" section on page linked below.
Good summary of wet/dray season from Smithsonian research
station site below.
"The Dry Season generally begins around mid-December, but this may vary by as much 3 to 4 weeks. Around this time, strong northeasterly winds known as “trade winds” begin to blow and little or no rain may fall for many weeks in a row. Daytime air temperatures increase slightly to around 30-31ºC (86-88ºF), but nighttime temperatures remain around 22-23ºC (72-73ºF). Relative humidity drops throughout the season, reaching average values as low as 70%.
The Wet Season usually begins around May 1, but again this may vary by 1 or 2 weeks. May is often one of the wettest months, especially in the Panama Canal
area, so the transition from the very dry conditions at the end of the Dry Season to the beginning of Wet Season can be very dramatic. With the arrival of the rain, temperatures cool down a little during the day and the trade
winds disappear. Relative humidity rises quickly and may hover around 90 to 100% throughout the Wet Season."
