Figure 4: The interior November 2011

Number of rain days RR >=3.0 mm

 

The stations Donderskamp, Godoholo and Washabo have noted the highest number of rain days (11) with more or equal to 3.0mm rainfall for one day. A maximum daily precipitation of 60.5mm is recorded at Botopasie.

The general review

The coastal zone and the inland country have recorded monthly area rainfall averages of 184.9 mm and 71.2 mm. The coastal zone monthly average is higher than the long term monthly coastal zone average (110.7 mm) and on the other hand, the interior area average is below the long term monthly interior average (85.4 mm).

A maximum monthly sum is measured at Domburg (266.3 mm). The highest number of rain days for November with daily rainfall equal or greater than 3.0 mm is 19 days. Furthermore, a maximum daily rainfall has been recorded at Lelydorp (77.1 mm) and at Botopasi (60.5 mm).

 

The overall rainfall average for Suriname (the coast and the inland) is 118.0 mm and this amount is higher than the long term November rainfall average (98.1mm). The coastal area is relative wet in comparison with the inland. Even though, the above mentioned values are all below the stated 200mm rainfall, conclusion is drawn that November is relative wet.
