Weather in Zapopan in May

Shoulder season. May is shoulder season in Zapopan — cheaper, quieter, and a genuine gamble. Highs average 33.4 °C, lows 17.4 °C, and rain falls on 6 days — nothing in the month is working against you.

May ranks 11 of 12 — near the bottom of Zapopan's year. January is the month that works, and the swing between the two is 46 points, which is a different holiday rather than a slightly better one.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 33.4 °C days and 17.4 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 8 days clear 35 °C, so a serious heatwave is normal rather than notable; the day swings 16 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest May day reached 37.9 °C and the coldest night fell to 10.1 °C.

This is the volatile part. May rainfall has ranged from 1 mm to 84 mm across the twenty years measured — a 83 mm spread around an average of 28 mm. The average is real but almost no individual May looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 6.1 km/h, so the temperature on the page is close to the temperature on your skin, and the air is dry at 39% humidity, which makes the heat far more bearable than the same figure somewhere humid — and dehydrates you faster than you expect.

How May sits in the year

This is a turning point in the year — April and June sit on opposite sides of it, so the month contains the change rather than following it. Rain is the thing that moves: June brings 15 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in May

May is at or near the longest days of Zapopan's year: 13.1 hours of daylight, gaining 0.4 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 23.7 °C between the year's warmest afternoons and coldest nights. At 1565 m, altitude is doing as much work here as latitude: thinner air means fierce sun by day and heat that leaves the moment it sets. Within May itself the daily swing is 16 °C, so mornings and afternoons need different clothes.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

May in Zapopan versus nearby

If Zapopan is one option among several, the nearby comparison is worth making. Morelia is a better bet in May — 3.1 °C cooler, 3 days more rain. San Luis Potosí is a better bet in May — 2.8 °C cooler, 1 day more rain.

So: May is a compromise. January is 35 points better and is what Zapopan is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
