This is why two out of every three attacks re concentrated in the least problematic months in weather terms, from March to May and from September to November. 160 140 120 100 80 60 40 20 0 ENERO FEBRERO MARZO ABRIL MAYO JUNIO OCTUBRE NOVIEMBRE JULIO AGOSTO SEPTIEMBRE DICIEMBRE Image 5: Somali pirate attacks by months (2005-2011) Pirates are active over 24-hour periods, although they are especially concentrated between 7 and 10 in the morning, local time. The percentage of threats that take place at dawn or dusk remain stable over the course of the time series. One in every six incidents takes place at night. The reality described is not uniform for all of the areas analysed. Some regions move a little away –or not at all- from the stated pattern (Gulf of Aden, Somalia, Indian Ocean, the Red Sea, the Seychelles, Oman); but in others, night-time incidents are more common, as happens in Tanzania (with 48% of the total) and Kenya (26%); or they fall below the average rate, such as in Yemen (4%) or India (no case reported).
