Cancun Weather Averages

Cancun Weather Averages

Cancun weather averages month by month demonstrate that the coldest months in Cancun are December and January but even then they still offer plenty of 80 degree plus days. Through January, February, March and April the temperatures increase steadily leading to my favorite time of year in Cancun, May.

Thereafter, we have the hottest months of the year in June, July and August with September not very far behind and then temperatures start to diminish through the fall months of October and November.

The table below shows Cancun weather averages and statistically is a much more accurate reflection.

There are two rainy seasons from May through to June and then October through to December.

Rain can be heavy at times in Cancun, but it is unlikely to rain for the whole of your trip. Often a heavy downpour will be followed by bright sunshine an hour later.

Cancun weather is a strange phenomenon. Often in downtown Cancun it can be raining, while only a mile further away in the Hotel Zone its blue skies and sunshine.

Often, the Cancun weather forecast is notoriously unreliable and often seem far more pessimistic than is the actual case. In particular, you should be wary of the ‘chance to rain’ figure which is often quoted.

If there is a 50% chance of rain this does not mean there is an even chance of it raining all day everywhere in Cancun or not. What it actually means is that there is a 50% chance that some rain may fall in some part of Cancun.

It doesn’t predict how heavy the rain will be, where it will fall or how long it will last. So the prediction may be considered accurate even if a few drops of rain fall for a minute in a very localized area of Cancun.

For this reason you should always take the weather forecast with a pinch of salt. It’s common for rain to be predicted every day at certain times of the year, but often I never see a drop. It probably rained somewhere, but not on me!
