Choosing the best time to travel

Our model analyses 10 years of ERA5 data to determine the ideal months based on three criteria: rainfall, temperatures and sunshine. Scores include ECMWF seasonal corrections to maximise accuracy at 1–6 months.

How it works

Enter a city and a date — the tool calculates a weather score from 0 to 10 based on historical records, then refines it with ECMWF seasonal trends. Annual mode lets you compare all months at once to find the optimal window. View full methodology →

Why are these estimates reliable?

BestDateWeather is not a 1-year weather forecast. We analyse seasonal climate trends to estimate the most probable conditions for a given date.

📊

10 years of observed data

Every estimate is based on real weather records from 2016 to 2025: temperature, precipitation, sunshine and wind, hour by hour.

🌍

ECMWF model integrated

For dates within the next 7 months, seasonal trends from the European Centre for Medium-Range Weather Forecasts correct the historical averages.

📐

Probabilistic score P10–P90

The score out of 10 is not an exact forecast. It quantifies the probability of good conditions by aggregating 4 key factors: rain, temperature, wind, sunshine.

What is the best time to travel?

Choosing the ideal date involves far more than a 5-day forecast. Average temperatures, rain risk, sunshine, wind — every destination has its own climate rhythm. BestDateWeather analyses this data to give you a probabilistic estimate of expected conditions, month by month or day by day up to a year ahead.

How to read the weather score?

The score out of 10 combines four weighted components: rain probability (highest weight for beach and travel), temperature against the ideal range for the activity, sunshine measured in hours of direct radiation, and wind speed. The P50 statistical median is used instead of the mean to prevent exceptional events — heatwaves, isolated storms — from skewing the estimate.

Weather for big decisions

An outdoor wedding, an important trip, a shoot, a sporting event — when weather truly matters, a simple 7-day forecast app is not enough.

BestDateWeather analyses seasonal climate trends to help you choose the most favourable moment, with a transparent method and verifiable data.
