Wanneru vs World: Temperature Compared
Wanneru's average annual maximum temperature is 25°C (77°F). To put that in context, here's how it compares to a few well-known destinations:
Rome, Italy averages 20°C (68°F) annually, with reliably warm summers and comfortable winters.
Interlaken, Switzerland averages 8°C (46°F) a year, with cold winters and cool summers thanks to its Alpine setting.
Beijing, China averages 20°C (68°F) annually, but with big seasonal swings — very cold winters and hot summers.
Adelaide, Australia averages 21°C (70°F) a year, with warm summers, mild winters, and relatively low rainfall year-round.
What Does the Temperature Feel Like in Wanneru?
Temperature alone doesn't tell the whole story — humidity plays a big role in how warm or cold it actually feels. High humidity in summer makes the heat feel more intense, particularly once temperatures climb above 25°C. In winter, the same humidity can make cold air feel sharper than the thermometer suggests.
In Wanneru, July is the coolest month, with average highs of 19°C (66°F) and humidity around 57% — considered moderate. In February, the warmest month, temperatures average 31°C (88°F) with 38% humidity — conditions that feel low. For a full picture, see our humidity page.
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.
