Seasonal Climate Variations / When to Go

To cope with the constant and somewhat unforgiving high temperatures and extreme summer climate, locals in Mesa make the most of air conditioning, choosing not to venture outside during the heat of the day, where possible. Instead, the balmy late afternoons and evenings are the time to socialise, shop, eat and sightsee, and many local stores and malls therefore choose to open well into the evening.

When it comes to rainfall in Mesa, average monthly precipitation levels are between 0.1 cm / 0.05 inches (June) to around 2.5 cm / 1 inch (January and February). During the winter months, only a few days, on average, experience minor overnight frosts, meaning that snow is therefore a rather unusual occurrence, particularly since daytime temperatures in January and February (the coldest months) are comfortably in double figures and close to 19°C / 66°F or 20°C / 68°F on the warmest, sunniest days.
