You couldn't predict your way out of a paper bag.

I'm having a hard time finding my way around this site. How do I search for long term weather forecast, looking for June 2018.

No more snow...

Some of us would agree with that! And some would say, “it’s still winter, after all!” We do hope that you get the weather you want!

November 2018

Is there any way to get a November 2018 prediction now? I’m planning an event n November 2018 I need to know what to do. Please advise thank you

November 2018

Over the years I look forward to checking your long range forecast predictions for different events and have been amazed at the near accuracy. I am looking now for a date in November 2018 and it seems the Almanac stops after October 2018. When will the November calendar appear?

weather forecast periods

The Editors's picture

For as long as we have been making weather predictions, they have begun in November and continued through the following/next year’s October. That is the traditional farming season (Nov being the time to put away tools, rest, and prepare for the next year). The winter period corresponds with the meteorological seasons (not the calendar): Nov through March is winter; April and May are spring; etc. So the forecasts begin after the traditional close of the farm/garden season and the beginning of the meteorological winter.

The Calendar Pages include Nov and Dec of the prior year for similar traditional reasons, but also because the Almanac is available in the autumn; people centuries ago and today use/d the last two months as well as the entire calendar cycle (Jan through Dec) as it appears in the Almanac.

March 2018
