  From 
  these 
  it 
  is 
  evident 
  that 
  the 
  Gold 
  Coast 
  is 
  the 
  Colony 
  of 
  least 
  rainfall 
  in 
  West 
  

   Africa. 
  In 
  the 
  coast 
  region 
  the 
  maximum 
  rainfall 
  generally 
  occurs 
  in 
  June 
  and 
  tails 
  

   off 
  rapidly 
  ; 
  in 
  Coomassie 
  it 
  is 
  more 
  evenly 
  distributed 
  from 
  May 
  to 
  September 
  ; 
  

   while 
  in 
  the 
  Northern 
  Territories, 
  July, 
  August 
  and 
  September 
  may 
  be 
  taken 
  as 
  the 
  

   months 
  with 
  the 
  greatest 
  rainfall. 
  During 
  these 
  three 
  months 
  nearly 
  three-quarters 
  

   of 
  the 
  rainfall 
  for 
  the 
  year 
  occurs. 
  

  

  The 
  smallest 
  rainfall 
  on 
  the 
  coast 
  is 
  in 
  the 
  low, 
  sandy 
  plains 
  east 
  of 
  the 
  Volta 
  

   Kiver 
  ; 
  it 
  increases 
  westwards 
  with 
  the 
  spread 
  of 
  the 
  forest, 
  culminating 
  in 
  the 
  region 
  

   around 
  Axim. 
  It 
  is 
  very 
  heavy 
  in 
  the 
  forest 
  belt 
  which 
  passes 
  through 
  Tarkwa, 
  

   but 
  diminishes 
  northwards 
  where 
  the 
  monsoon 
  forest 
  gives 
  way 
  to 
  savannah 
  forest, 
  

   and 
  is 
  least 
  in 
  the 
  Northern 
  Territories 
  in 
  the 
  savannah 
  region. 
  The 
  dry 
  season 
  

   proper 
  in 
  the 
  hinterland 
  is 
  from 
  November 
  to 
  April, 
  when 
  practically 
  no 
  rain 
  falls. 
  

  

  The 
  general 
  humidity 
  is 
  least 
  during 
  the 
  dry 
  season, 
  but 
  is 
  not 
  proportionate 
  to 
  

   the 
  rainfall. 
  The 
  towns 
  on 
  the 
  coast, 
  on 
  account 
  of 
  their 
  proximity 
  to 
  the 
  sea, 
  

   possess 
  a 
  higher 
  relative 
  humidity 
  than 
  the 
  recorded 
  rainfall 
  would 
  lead 
  one 
  to 
  

   expect, 
  and 
  further, 
  there 
  is 
  always 
  a 
  heavy 
  dew 
  and 
  thick 
  mist 
  to 
  about 
  8 
  a.m. 
  in 
  the 
  

   rain- 
  and 
  monsoon- 
  forest 
  zone 
  ; 
  this 
  increases 
  the 
  relative 
  humidity 
  in 
  these 
  regions.
