WorldVacayWeather is an independent project that turns about twenty years of historical climate records into clear, honest answers about when and where the weather is likely to suit your kind of holiday.

Booking a trip is the easy part; judging whether the weather will actually suit you is the part most travellers guess at. WorldVacayWeather exists to replace that guesswork with something steadier. We take long-run climate records and turn them into a plain answer to a practical question: in the dates you can realistically travel, which places have usually offered the kind of weather you want, and how closely? We are not trying to sell a destination or a particular week. The aim is honest expectation-setting, so you can plan with a clearer idea of what is typical rather than hoping for the best and discovering otherwise on arrival.
Everything on the site is built on free, open historical weather data from the Open-Meteo Historical Weather API, which serves the ECMWF ERA5 reanalysis: a continuous, gridded record reconstructed from observations and modelling. For a given place we read roughly twenty years of daily records, ending with the last full calendar year and reaching back nineteen years before that, and keep only the calendar days that fall inside your chosen dates. For those days we average mean, maximum and minimum temperature, total precipitation, sunshine duration and maximum wind speed, then grade each figure against the preferences you set for warmth, sun, wet days and wind. The four parts are combined into a single score out of one hundred. This drives five tools: Weather Check grades one place over set dates or finds its best month; Discover ranks destinations by how well their typical climate fits your profile; the year calendar lays a whole year out week by week; the Packing List turns the expected climate into a suggested kit list; and the Budget Estimator gives a typical planning cost. A separate guides hub collects longer reading on how to interpret all of this. One point matters above all: these are long-run climate averages, not a forecast for your specific dates.
WorldVacayWeather is an independent project. It is not owned by, affiliated with, or paid by any tour operator, airline, hotel chain or booking platform, and no destination can pay to be ranked more favourably. The core tools are free to use, with no account required to run them. The running costs are covered in two ordinary ways: display advertising shown alongside the content, and optional affiliate links, where we may earn a small commission if you choose to book through a partner at no extra cost to you. We do not sell or trade your personal data, and the scoring is never adjusted in favour of an advertiser or affiliate. Keeping the funding plain and the rankings independent is deliberate, because the tools are only useful if you can trust that the numbers are not for sale.
WorldVacayWeather is a small, independent project run from the Netherlands rather than a large company with a marketing department. It is built and maintained on a modest scale rather than by a large team, which keeps the scope focused and the voice consistent across the tools and the written guides. Because it is small, feedback genuinely shapes what gets built next: corrections to the climate explanations, requests for destinations that are not yet covered, and notes on anything that reads as unclear are all welcome. The most useful thing you can do is get in touch through the contact page, which is the best route for questions, suggestions and reporting anything that looks wrong.
