2026 Wimbledon Championships: Which Day Is Rain Most Likely?

Even if you are watching the action under the retractable roofs on Centre Court or No.1 Court, rain can still dampen your spirits.

If you are planning to attend the Tournament in 2026, is there anything you can do to choose a day with the lowest probability of rain?

What happened in 2024

Persistent rain affected Wimbledon more than usual in 2024, causing the Mixed Doubles final to be moved from its original Thursday slot to Sunday.

Wimbledon has several contingencies for bad weather, including indoor play. However, this is unlikely as the covered two main courts can be utilised more. Also, the addition recent middle-Sunday rest day means Wimbledon is now played over 14 days instead of 13.

What are the dates of the 2026 Championships?

The Wimbledon Tournament dates very slightly from year to year, but the start date is usually the Monday that falls closest to 1 July. This means that the 14-day event could start in late June or early July.

The 2026 Wimbledon Tennis Championships will run from Monday, 29 June 2026 to Sunday, 12 July 2026.

Which courts have retractable roofs?

Centre Court and No.1 Court both have retractable roofs. If it rains, play will usually continue on these two main Show Courts.

Play will typically be halted due to rain on Wimbledon’s outdoor courts. Play will resume when the umpires decide that the conditions are suitable.

Probability of rainfall

It is estimated that weather forecasting has improved to the point where the 4-day forecast is now as accurate as the 1-one day forecast was 30 years ago.

According to meteorologists, however, predicting rainfall is particularly difficult as showers can be very localised.

Unless you are looking for tickets a day or two in advance, the forecast won't be much help if you are looking for a guaranteed rain-free day.

To try and establish whether the historical records offer any insights, we looked at the rainfall data over the past 10 years as follows:

When plotted, the significant variation in the average amount of daily rainfall over the Tournament is immediately apparent:

Conclusion

It is of course impossible to extrapolate historical weather data to indicate future weather. That said there, are seasonal trends.

London has 106 days of rainfall per year (in excess of 1mm per day) on average. Even before you seasonally adjust this statistic for the Summer, you would have a 70% chance of fair weather at the Tournament.

According to the historical data, the two days between 2011 and 2022 with the lowest rainfall were 30 June (0.14mm) and 1 July (0.16mm). Both days are typically around the first day of the Tournament.

The day with the third lowest rainfall was 15 July (0.22mm) - typically around the day of the finals.

The day with the highest average (7.23mm) rainfall was 12 July.
