“Allergy season” isn’t one season - it’s three overlapping ones, each driven by a different pollen. SafeInhale tracks all three: tree, grass, and ragweed. Figuring out which one is yours is one useful step for understanding your symptoms.
Tree pollen - the first wave
Peak: late winter through spring (roughly February–May).
Trees are the early risers. Oak, birch, cedar, maple, and ash release enormous amounts of pollen on warm, dry, breezy days. A single oak can put millions of grains into the air, and they travel for miles.
If your symptoms start while it’s still chilly and ease up by early summer, tree pollen may be contributing to your symptoms.
Grass pollen - the summer staple
Peak: late spring through summer (roughly May–July).
Grass is the most common allergy trigger worldwide. Counts climb on warm afternoons and spike when lawns are mowed. If your worst days are sunny summer ones - especially right after the lawn gets cut - grass pollen may be one of your triggers.
Ragweed - the fall finale
Peak: late summer through fall (roughly August–October).
Ragweed is the classic cause of fall hay fever. One plant can release up to a billion grains in a season, and they ride the wind for hundreds of miles. If you feel fine all summer and then fall apart in September, ragweed may be contributing to your symptoms.
Why this matters
Once you know your trigger, you can:
- Ask your healthcare professional whether starting allergy medication before your usual allergy season is appropriate for you.
- Set it as your trigger in SafeInhale so your Breathe Score warns you specifically on high days for that pollen.
- Plan outdoor time around the daily forecast instead of guessing.
