WorldVacayWeather is a holiday-weather planning tool for travellers who choose where, and when, to go based on the climate rather than the brochure. Most trips are booked around dates that suit work and school, then the weather is left to chance. This site flips that order. It looks at what the weather has actually done at two dozen popular holiday destinations over roughly the past two decades, and helps you match those long-run patterns against the conditions you personally care about: how warm you want it, how much sun, how little rain, how much wind you can tolerate. It is built for the traveller weighing up Crete in May against the Algarve in September, or wondering whether the Maldives in your only free fortnight is a sensible idea. The aim is honest expectation-setting before you commit money to flights and accommodation, not a promise that any given week will be perfect.
Every figure on the site comes from the free Open-Meteo Historical Weather API, which serves the ECMWF ERA5 reanalysis: a continuous, gridded record reconstructed from observations and modelling. For each of the 24 destinations we read about twenty years of daily values at that place's coordinates, covering mean temperature, sunshine duration, precipitation and wind speed. Those daily records are averaged and then scored against your saved weather preferences, with temperature carrying the largest weight (roughly 35%), rain and sunshine an equal middle weight (roughly 25% each), and wind the least (roughly 15%). Five tools sit on top of that data: check a single destination for specific dates, discover destinations ranked by how well they fit your preferences, view a full year as a month-by-month calendar and heatmap, generate a packing list from the expected climate, and produce a rough trip budget estimate. One point matters above all: these are long-run climate averages, not a forecast. They describe what is typical for a place and time of year, not what the sky will do on your particular dates.
No. Every number on the site is a long-run climate average built from roughly twenty years of historical daily records, not a prediction for your specific dates. It tells you what is typical for a place at that time of year, which is reliable for planning months ahead, but it cannot tell you whether your particular week will be sunny or wet.
It comes from the free Open-Meteo Historical Weather API, which serves the ECMWF ERA5 reanalysis. ERA5 is a respected scientific dataset that reconstructs past weather worldwide from observations and modelling. We read about two decades of daily values at each destination's exact coordinates and average them for the relevant period.
There are 24 destinations covered, chosen as popular holiday locations across Mediterranean, tropical, desert, temperate and Arctic-influenced climates. Each is scored from its own historical record, so you can compare like for like rather than relying on a vague sense of which place is usually warmer or drier.
Each destination's averaged temperature, sunshine, rainfall and wind are compared against the weather preferences you set. The components are combined into a single score out of 100, with temperature carrying the largest weight, rain and sunshine an equal middle weight, and wind the least. A higher score means the typical climate sits closer to the conditions you said you wanted.
Yes, always. This site is for the planning stage, when you are choosing where and roughly when to go and a real forecast does not yet exist. Once you are within about a week of departure, check a standard short-range forecast for the actual conditions and pack accordingly, using our climate view as background context.
A low score only means the typical climate for the dates you entered is far from the preferences you set, not that the place is bad. Try other months on the calendar: many destinations that disappoint in peak summer or deep winter score well in the shoulder seasons, so the timing is usually the issue rather than the destination.
