Mazatlán weather in September

Forum posters consistently rate November as one of Mazatlan's best months, some rating it even nicer than February, with warm days, warm evenings and humidity finally easing off after running high most of the year. Posters do flag that hurricane season technically extends into November, recommending keeping an eye on tropical weather updates and having travel insurance in place just in case. Posters cite the eight-month dry stretch from November through June as averaging only about 4.4 inches of rain total, underscoring how reliably dry this window runs. Posters generally rate November as close to perfect for Mazatlan, pairing great weather with lower crowds and a town gearing up for the holiday season.

Forum posters describe early May as close to ideal - daytime temperatures typically 80-90F, clear skies, essentially no rain and few bugs, with evenings called genuinely perfect. Posters note February through May counts as an almost completely rain-free stretch (barely a tenth of an inch of precipitation a month), and locals reportedly run an informal betting pool each year on which day the rainy season's first real storm lands - nobody who actually lives in Mazatlan picks a date before mid-June. Beyond the weather, posters call May a noticeably quiet month for foreign tourists specifically, though weekend visitor numbers from elsewhere in Mexico have picked up in recent years thanks to improved highway access.
