Cap-Haïtien vs World: Temperature Compared
Cap-Haïtien's average annual maximum temperature is 28°C (82°F). To put that in context, here's how it compares to a few well-known destinations:
Lisbon, Portugal averages 21°C (70°F) annually — warm summers, mild winters, and rain mainly in the cooler months.
Glasgow, Scotland averages 13°C (55°F) a year — mild but often grey, with cold winters and rarely hot summers.
New York City, USA averages 17°C (63°F) a year, with hot humid summers and cold winters that bring regular snowfall.
Perth, Australia averages 25°C (77°F) annually, with a classic Mediterranean climate — hot dry summers and mild wet winters.
Climate temperature data is typically calculated as a 30-year average. This smooths out year-to-year variability and gives a more reliable picture of what a place is actually like, rather than what happened in any single unusual year.
The readings come from a range of sources — land-based weather stations, ocean buoys, ships, and satellites. That data is collected by weather services around the world, then pooled, quality-checked, and averaged to produce the climate records you see here.
Land Temperature: The average surface temperature across the Earth's land is around 14°C, but that figure hides enormous variation. In the Sahara, daytime temperatures can exceed 50°C. At the poles, averages fall below -30°C. Deserts are also notable for how quickly they cool at night — without moisture in the air to retain heat, temperatures can drop 30°C or more in just a few hours, making desert nights surprisingly cold.
Sea Temperature: The oceans average around 17°C at the surface — generally cooler than land. Because water absorbs and releases heat slowly, the sea acts as a buffer, keeping coastal climates more stable than inland areas. The deep ocean is a different story: below the sunlit upper layers, water stays near-freezing regardless of surface conditions.
Equatorial Regions: Near the equator, the sun is overhead year-round, producing consistent heat and fuelling tropical rainforests in places like the Amazon and Congo basins. Seasonal temperature variation is minimal, but these regions do experience distinct wet and dry seasons that shape their ecosystems.
Desert Regions: Desert temperatures swing wildly between seasons and even between day and night. The Sonoran Desert in North America can drop to 0°C on winter nights yet exceed 40°C on summer days. What all deserts share is very low rainfall — typically under 250mm per year.
Polar Regions: The Arctic and Antarctic experience extreme cold, with long stretches of darkness in winter and continuous daylight in summer. Arctic winter temperatures average around -30°C. In Antarctica's interior, it gets far colder — sometimes below -80°C in the coldest recorded spots.
Temperate Forests: Across North America, Europe, and East Asia, temperate forests see proper seasons — warm summers and cold winters, with average temperatures roughly between 5°C and 22°C depending on the time of year.
Mountain Regions: Temperature drops by roughly 6°C for every 1,000 metres of altitude. In ranges like the Andes or the Himalayas, that means you can move from temperate forest at lower elevations to permanent snow and ice at the peaks, all within a relatively short distance.
