The average high temperature ranges between 28C (82F) in December to 35C (94F) in May which is considered as the hottest month by the Meridianos. The average lows range from 17C (62F) in January to 23C (73F) in July. November to April are considered the dry months with very little precipitation. The rainy season encompasses the months of June/July to August/September. We have found that there are days where it rains frequently but that generally the days start off with sunshine, get cloudy around noon, rain at 3 o'clock and the clouds clear up 5 o'clock. There are many days where the daily rains don't materialize. Some of the daily rains can be impressive deluges but the gravelly soil absorbs the water quite quickly and doesn't impair travel or movement.

The tropical weather provides the blessings of magnificent varieties of fruit; exotic and familiar. In Ka'an has 30 some odd varieties of fruit ranging from oranges, limes, bananas to carambola, mangoes, caimito, pitaya, nopales and many others. The citrus trees will bear fruit all year round provided they receive water frequently. The others bear fruit at different times of the year but principally in the summer months. For the adventurous consumer this is a marvelous time to visit the tropics. Tropical flowers are gorgeous; birds of paradise, bugambilias, tulipanes, jasmine de la noche and a host of others decorate the grounds at In Ka'an.

Clothing standards are very casual. Wash and wear cotton shirts, shorts and t-shirts are good day-time wear. The local Meridiano is seldom seen in shorts and the "formal" wear includes the marvelous guayabera which is a short sleeve shirt worn by the local business man. Linen and cotton clothing is available in many of the local shops. Wear long pants and sweaters as the evenings in the winter can be surprisingly cool. Bring sandals and comfortable walking shoes.
