Weather guide

Weather in Oaxaca

Oaxaca-area ERA5 estimates for 1991–2020 favour November–February for relatively dry visits with milder afternoons. March–April are hotter, while summer brings substantially more rain. These are modelled grid estimates rather than station normals or a forecast. Pack light daytime clothing, a removable layer and shoes for uneven paving.

24–28°C

Warm afternoons and cooler mornings.

October · representative month, not a forecast

Evenings: 13–17°C
Rain: Showers possible
Daylight: Check actual sunrise and sunset; plan unfamiliar routes in daylight.

What this means for packing

October needs light daytime layers and accessible rain cover. Choose shoes that grip wet paving and a sweater for a late return. Any Day of the Dead event or cemetery visit needs a current programme and respectful local access checks.

Choosing a season

The best-season badge suggests months for general sightseeing, using the typical daytime temperatures and rainfall in our monthly guides. Beach holidays, festivals, winter sports and northern lights trips may suit different dates.

Climate methodology

Packtricia calculated October Oaxaca-area ERA5 reanalysis averages via Open-Meteo for 1991–2020: mean daily high 26.4°C, mean daily low 15.1°C and mean monthly precipitation 70.8mm. Thirty complete year-months are equally weighted using daily high/low means and monthly precipitation sums. Requested coordinates 17.0732,-96.7266 returned grid 17,-96.75 at 1592m model elevation. These are gridded estimates, not station normals or forecasts. Display bands extend rounded means by 2°C each way and do not bound extremes. Rain totals are not wet-day probabilities or a promise of afternoon-only showers.

Transport guide

Getting around Oaxaca

Use the official BinniBus app for metropolitan bus routes, stops, arrival estimates and notices. Its Android and iPhone download links are on the operator’s app page. BinniBus covers its own Oaxaca metropolitan network; do not assume it supplies airport transfers, intercity tickets or a direct bus to Monte Albán.

BinniBus official Android and iPhone downloads
Follow the official store links, then check the route and direction before boarding. Route information is separate from paying the fare; downloading the app does not activate a ticket.
BinniBus routes and service notices
Check the current route map and notices for your stop. Routes and payment arrangements can change; the old December–January free-travel announcement is not a current fare promise.
Operator payment instructions
The published service instructions permit cash deposited on boarding or an authorised prepaid card passed over the reader. Confirm the current arrangement for your route, carry small cash and validate a funded card when boarding. App-based ticket purchase or activation is not confirmed.

Check the operator’s current service notices and ticket instructions before travelling.
