About CityTimeWeather

CityTimeWeather is a free tool for checking the current local time and weather in cities around the world, side by side. Instead of juggling a separate clock and a separate forecast, you get both at a glance for any place you search.

What makes us different

Most weather sites stop at today's forecast. We pair live conditions and a 5-day outlook with something harder to find: real historical climate data. For our flagship cities we publish month-by-month averages — typical highs, lows, rainfall, sunshine, wind, and snow days — drawn from decades of recorded observations, so you can plan a trip around what a place is actually like in, say, October rather than guessing.

How the climate guides are made

Each flagship city guide is computed, not copied. We take ten full years of daily records (2015–2024) for that city's coordinates and reduce them to monthly figures: the average daytime high and overnight low, the typical monthly rainfall total, daily sunshine hours, peak wind speeds, and how many days brought snowfall. From the same data we derive the practical answers — the warmest, coldest, wettest, and sunniest months, and the window with the most comfortable weather for a visit.

Every guide also includes a long-term warming comparison: we run the same monthly averaging over 1950–1959 and put the two decades side by side. For most cities the shift is plainly visible — often one to three degrees in the warmest month — and because both windows span ten years, the comparison reflects climate, not one freak season. You can see all fifty cities ranked on our warming cities report.

Numbers are stored in both metric and imperial, so the °C/°F toggle switches every table and sentence consistently — no mixed units, no rounding drift.

Where our data comes from

Live forecasts and historical records are sourced from the Open-Meteo open weather API, which builds on national weather services and the ERA5 climate reanalysis archive (data reaching back to 1940). Local time is computed from each city's IANA time zone. We process and summarise this data ourselves to produce the climate guides you see on city pages; any mistakes in that processing are ours, and we fix them when readers point them out.

What we cover

The site includes more than 500 cities across every continent — browse the full list on the all cities page. Around fifty of the world's most visited cities carry the deep climate guides described above, and pages are available in six languages (English, Italian, German, French, Spanish, and Portuguese) where a city has a strong local-language audience.

Who runs it

CityTimeWeather is an independent project built and maintained by a small team that loves maps, travel, and weather data. We are not affiliated with any government weather agency, and we don't sell your data — see our Privacy Policy for the details. If you spot an error or have a suggestion, we genuinely want to hear it.
