The climate in Belize

Average daytime and nighttime temperatures

All climatic diagrams of this page are taken from the collected data from 3 measuring stations in Belize.
All data correspond to the average monthly values of the last 20 years.

Back to overview: Belize

Climate zone: tropics

High humidity in Belize and high temperatures are causing a pleasant weather at times, but also and partly tropical hot and humid. It is warm to hot all year round and invites to bathe at average water temperatures of 29 degrees. Dued to the lesser rain the best time for traveling is from February to May. Most precipitation decrease from June to October.

Temperature records of the last 66 years

The hottest temperature measured from 1955 to June 2021 was reported by the Belize Phillip Goldson Airp weather station. In March 2003 the record temperature of 37.3 °C was reported here. The hottest summer from July to September, based on all 2 weather stations in Belize , was recorded in 1958 with an average temperature of 29.2 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 28.2 degrees Celsius.

The coldest day in these 66 years was reported by the weather station Belize Phillip Goldson Airp. Here the temperature dropped to 12.5 °C in January 2001. Belize Phillip Goldson Airp lies at an altitude of 5 meters above sea level. The coldest winter (January to March) was in 1978 with an average temperature of 23.5 °C. In Belize, it is usual to have about 1.6 degrees more at 25.1 °C for this three-month period.

The most precipitation fell in Oktober 2000. With 33.2 mm per day, the Belize Phillip Goldson Airp weather station recorded the highest monthly average of the last 66 years.

Long-term development of temperatures from 1998 - 2020

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 1 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1998 to 2020 there were only these 1 weather stations in the whole country, which reported continuous temperature values (Belize Phillip Goldson). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 2019 with 29.7 °C. 2010 was the coldest month with an average temperature of 22.2 °C.

The average annual temperature was about 26.7 °C in the years after 1998 and about 27.2 °C in the last years before 2020. It has therefore increased only slightly by about 0.5 °C over the past 23 years. This trend only applies to the selected 1 weather stations in Belize. A considerably more comprehensive evaluation of the global warming has been provided separately.
