In America, we have four seasons and base our Ayurveda guidelines as such:

Sharath Ritucharya

Sharath Ritu begins in the middle of September, and lasts until mid-November.

As we get one last surge of warmth and dryness after the rainy season, your agni, or digestive fire, regains its strength.
Water and fire are both prominent energies during this transitional time, which makes it the perfect period to begin to pacify those Pitta energies.

Hemanta Ritucharya

Hemanta Ritu blows in during the middle of November, and lasts until the middle of January.

During this time, your agni is at its strongest.
The elemental energies of earth and water are dominant.
Fiery Pitta becomes grounded and pacified.

Shishira Ritucharya

The cold settles in for a few months in Shishira Ritu, which lasts from mid-January until mid-March.

This wet, cold season brings with it an increase in heavy Kapha energies.
Your agni needs to burn even brighter to keep things balanced.

Vasanta Ritucharya

As nature begins to stir back into life, we transition into the Dakshinayana, or the warmer months. Vasanta Ritu lasts from mid-March to mid-May.

Earth and air energies combine to make this time a lively transitional period.
Kapha energies start to disperse, which douses your agni and can cause a lot of discomforts.

Grishma Ritucharya

It’s summer! Grishma Ritu lasts from Mid-May to Mid-July.

Fire and air energies dominate this season, drying things out and increasing both the Pitta and Vata energies within the body.
Your agni is at an all-time low, so keeping things light is a must.

Varsha Ritucharya

Varsha Ritu takes place from mid-July to mid-September.

This is typically a wet, rainy season, with earth and fire energies rising to the forefront.
Your agni is heavily dampened during this season, so it’s time to get that fire roaring again.
