To help you pick the right holiday destination, use our bespoke weather comparison tool to pit two places against each other, and see exactly how they measure up in the areas that matter most to you. Get started by choosing two destinations above.
Weather comparison tool: Compare destinations
From temperature to the amount of sunshine to expect, you can compare average weather conditions for every country in the world to help settle any discussion about where you should go for your next holiday in the sun. Our weather comparison tool uses 30 years worth of data to calculate long term monthly averages for every country in the world.
Choosing a destination with the right weather is crucial when it comes to booking your holiday. No one wants to go away and realise too late that they've arrived in the Med when the sea is at its coldest, the Indian Ocean when there's little sunshine, or the Far East during the monsoon - your time off is too precious to get it wrong.
How to use the weather comparison tool to compare two destinations
Hopefully you will find our weather comparison tool easy to use. Simply fill in your chosen destinations, and you will be able to see up to four graphs comparing the following average monthly weather conditions, including:
- Temperature: compare average daily maximum temperatures
- Hours of sunshine: compare average daily hours of sunshine
- Days with some rainfall: compare average number of days with some rainfall
- Sea temperature: compare average sea temperatures
Note: The sea temperature graph will only be displayed if both destinations which are being compared are by the sea.
The weather comparison tool lets you see quite quickly whether you have a clear winner for your next holiday spot, or if the two you have chosen to compare have very similar conditions. You can find details of these and other weather conditions for all destinations in our individual climate guides.
