Discover the last 30 years of weather statistics in any city in the world to plan your big day.
Planning a wedding takes months. Waiting for the week before only creates last-minute panic without solutions.
We audited our own predictions against actual weather recorded across 270,928 wedding Saturdays in 413 cities. 100% transparent.
Comparison between our forecast and real observations
When we show a 20% (2 in 10) rain chance for your date, does it actually rain 2 out of 10 times? The historical evidence proves it:
Why this matters: regular weather apps aren't calibrated for wedding dates. Our engine ensures that published percentages match real historical frequency.
Ensure guests stay comfortable all day and night
It is not just about rain. Knowing if you need jackets at midnight or shade during the afternoon is critical for planning:
7 in 10
Exact hit on daytime temperature (within ±3 °C)
8 in 10
Exact hit on night temperature (jacket decision)
±2.3 °C
Average margin (smaller than sun to shade difference)
When warning about extreme heat (over 30 °C), we hit 7 in 10 times. Perfect to arrange fans, parasols, and hydration stations.
We use NASA POWER (MERRA-2 / IMERG), with real daily data from 1996 to 2025. For each city and date we look at the 15 days centred on that date across all 30 years: about 450 measurements. The percentage of those days that exceeded 1 mm of rain is the number we publish.
To check accuracy we use leave-one-year-out validation: we recompute each day's probability using only the other 29 years, then compare it with what actually happened that year. Testing on the same data used to build the prediction would prove nothing.
We don't publish an overall "hit rate" because it would be misleading: since rain is uncommon, always answering "no rain" would be right 67.1% of the time on these Saturdays while saying nothing useful. The right test for a probability is whether it holds up, which is what the table above shows. Technically, the Brier skill score against using the regional average is 23%, and the average gap between what we say and what happens is 0.6 percentage points.
What we changed: until 2026 we computed the probability from just 5 years, counting any 0.1 mm record as rain (dew included). That model was off by 11.7 points and could show 80% rain for dates where it actually rains 14% of the time.
We count a day as "rained" at 1 mm or more. Temperature measured over 270,928 Saturdays. Last updated: 31/07/2026.
Over 120 cities across Spain, Mexico, Italy, France, Germany, the UK and growing. If your destination isn't listed, we'll add it.
We don't give you the monthly average: we give you what actually happened around June 14 (or whatever date) across 30 years, with the year-by-year breakdown.
Rain probability, average temperature, daylight hours, golden hour for photos and Plan B tips in under 10 seconds.

We generate your packing list automatically based on the forecast for each destination: clothes, footwear and accessories you will actually need.
We don't use long-range forecasts (they aren't reliable beyond 10 days). We use historical data: we look at what the weather actually did in your city around that date across 30 years. That gives a solid statistical probability — and we publish how far off we are.
Average, maximum and minimum daily temperature, expected millimetres of rain, precipitation probability, how often nights drop below 18 °C, sunlight hours and golden hour for photos. Year-by-year breakdown plus the 30-year normals.
