Precipitation Outlook - National Meteorological Service of Belize
Tropical Weather Outlook
  • For the North Atlantic, Caribbean Sea and Gulf of Mexico tropical cyclone formation is not expected during the next 48 hours.

Hurricane Tips
  •  Fill sinks, bathtub and large containers with water as an extra supply for washing and flushing.
  •  During the hurricane season, fisher folks are strongly advised to stay informed via radio, listen to the weather bulletin before venturing out to sea. Move your boat to safe harbor early.
  •  Prepare your car in case of evacuation. Fill your tank and check your tires.
  •  Upon alert, farmers should harvest crops which can be stored, consumed and sold.

Several agro-meteorological stations across the country are used to make the seasonal precipitation and temperature forecast. This is done by using available historical data, along with global and regional climate models, statistical models such as the Climate Predictability Tool (CPT) and Subjective Inputs.

Based on all these inputs the rainfall forecast for Belize for the period September-October-November 2017 (SON 2017) is for normal to slightly above normal rainfall for most of the country. Temperatures are expected to be above normal during this period.

Approximate rainfall amounts that are expected over different regions of the country during the period September-October-November 2017 are as follows:

REGIONRAINFALL AMOUNT (mm)CATEGORY
North (Orange Walk and Corozal Districts) 400-600 Normal – Above
Central Inland Areas (Cayo District) 500-800 Normal – Above
Central Costal Areas (Belize District) 800-1000 Above Normal
Southern Areas (Stann Creek and Toledo Districts) 900-1300 Normal – Above

The rainfall forecast for Belize for the period December 2017-January-February 2018 (DJF 2017-2018) is for normal rainfall over northern areas, slightly above normal rainfall over central areas and above normal rainfall in the south. Maximum temperatures are expected to be near normal during this period while minimum temperatures are expected to be above normal.

Approximate Rainfall amounts that are expected over different regions of the country during the period December 2017-January-February 2018 are as follows:

REGIONRAINFALL AMOUNT (mm)CATEGORY
North (Orange Walk and Corozal Districts) 100-200 Near Normal
Central Inland Areas (Cayo District) 300-700 Slightly Above
Central Costal Areas (Belize District) 400-500 Slightly Above
Southern Areas (Stann Creek and Toledo Districts) 400-600 Above Normal

What influences the next season? Recent observations show Sea Surface Temperatures (SSTs) in the equatorial eastern Pacific (NINO3.4) region hovering just below normal at around -0.4 degrees Celsius below average. Most global models suggest that temperatures should remain in that general range during the next few months which indicates neutral to weak cool ENSO conditions. Additionally, temperatures in the tropical Atlantic Ocean are also just above average. Warm conditions in the Atlantic, coupled with slight cooling in the Pacific (nino 3.4 region) suggests normal to above normal rainfall over our region. These factors are also likely contributing to the very active Atlantic Hurricane Season. However, there is always some level of uncertainty in predicting the major climate drivers and therefore users of this information are therefore ask to continue to monitor the monthly updates.
