What’s the Weather Really Like at Lake Chapala Ajijic ?

August 15, 2008

What’s the weather like in the Lake Chapala area? How does it affect our lives here?



At approx. 5,000 ft. above sea level, surrounded by mountains, and with the Lake our area has only a moderate temperature variation from month to month and season to season.


January through March our highs run from 76 to 81 degrees F. and the lows from 47 to 50 F. The rains are very slight from 0.2 to 0.5 inches.


April through June the highs run from 83 to 86 degrees F. and the lows from 54 to 61 degrees F. The rains continue light in April and May but increase dramatically in June to 6.3 inches on average.


July through September the highs run from 78 to 79 degrees F. and the lows from 59 top 60 degrees F. The rains continue heavy in July at 9.7 inches down to 5.8 inches in September.


October through December the highs run from 79 in October to 76 in December. The lows run from 55 F. in October to 47 F. in December. The rains taper off from 2.3 inches in October to 0.5 inches in December.

While the average temperature in Guadalajara may be nearly the same; the highs are higher and the lows lower there compared to our area.


In other words we are much more comfortable here at Lake Chapala in both the winter and summer than our nearby friends in Guadalajara. We also have moderate humidity most of the year.



With the clean mountain air, the perfect year around weather which encourages outdoor activities, and the fresh local food most North Americans who move here lose 15 pounds or so without really trying to do so. No promises OK?


Another by product of the wonderful weather is that we save a bunch on utilities here since we rarely need to heat or cool our homes artificially.


Warning: We regulate the temperature of our homes by how many windows and or doors we have open or closed.


Knowing this and knowing that most of the developments are located on the Northern shores of Lake Chapala that North Americans are interested in it’s a good idea to consider that the wind patterns are to and from the lake.


This means that it’s best to orient your home to take advantage of the breezes to and from the lake which generally means that your windows and doors should be on the North and South sides of your home if possible to enjoy the best breezes.


Homes oriented where the windows and doors are on the West and East side of the home due to neighboring property walls on the North and South sides often have open interior atriums to allow light and air to enter and exit the home. In such homes ceiling fans would be a wise investment.


The Lake has a wonderful moderating influence on our high and low temperature here at Lake Chapala Ajijic giving us a perfect micro climate year around. Why not come see for yourself?

    Sid, your explanation of the weather at lakeside was very informative. The breeze to be had sounds wonderful. I’ve read many times about the rain. It is said it rains mostly at night and you wake to sunshine. Being born and raised on the northern Oregon coast, I’ve grown to loathe rain. It depresses me horribly. So exactly how much does it rain during the day?
    Thank you
    Sarah and Ned

    HI Ned and Sarah

    Here’s a chart of the rain amounts by month:

    High Temp. 76 79 81 84 86 83 79 79 78 79 78 76

    AS you can see from the chart the rain is mostly in July, August and September,

    Why not plan a trip during the rainy season and you can determine just how the rain affects your level of depression.

    I think you’ll find it to your likening. The weather patterns are changing all over the world including here.
    Hope this helps some. Siempre tu amigo, Sid

    Thank you Sid for that weather article.You nailed it. I needed to know it all. I’m pleased to see that the temps are so perfect. Does it ever get above 85 out?
    We’re looking forward to meeting you and just hanging out at Lake Chapala. Thank you so much, Ned and Sarah

    Hi Ned and Sarah,

    Thanks for your nice comments. Yes, sometimes it gets above 85 F. but as long as you’re in the shade you’ll be comfortable and almost always there’s a breeze from the Lake.

    Orientation of your home on the lot here is more important than in the USA or Canada. We don’t set thermostats in our homes because we don’t have them. We just open or close windows to varying degrees to control the temperature in our homes. Thanks again, Sid

    Inquiring-Is there anywhere lakeside I can renew my soft contact lens? Or do I have to make a trip to Guad? Should I stash a supply before before arriving?
    Appreciate any help

  • http://www.chapalaclub.com Sid Grosvenor

    Hi Candis, Surely there must be . We have several Optometrists in the area. I would stock up in advance if I could get a good price.

    Perhaps there’s a club member who might know for sure. Tu amigo, Sid

    Hi Rosalie, Of course you can try to contact one of our local rental agencies, but if you know someone that lives in the area they could check the Lake Chapala Society Bulletin Board. between now and your arrival date.

    Since I was in the LCS area just before I published this I checked the board and found a 2 bedroom 2 bath in San Antonio for $600 USD short term available now. The telephone is (376) 766 1329 or cell is 331 3001716. Good Luck, Tu amigo, Sid

    We presently live in the Caribbean and are very acclimitised to hot weather. Anything under 70 degrees is really cold for us and we need the heating on. It sounds like properties in the Chapala area rarely have any central heating. Are we going to freeze if we move here? It’s the only thing stopping us – everything else seems perfect. But its just so cold!
