August 13, 2026 Thursday Tropical Update

Atlantic still watching a parade of tropical waves but hostile environment. Lala forecast to become a hurricane while impacting Hawaii

What the month did

August 2026 was the warmest August in the 132-year national record (1895–2026), at 75.6°F against a 1991–2020 normal of 73.1°F (+2.5°F).

August 2026 was the 22nd-driest August in the 132-year national record (1895–2026), at 2.3in against a 1991–2020 normal of 2.7in (-0.4in).

NOAA/NCEI Climate at a Glance, contiguous United States. This is the observed record for the month, not a score of anything said in this piece — the forecast ledger begins 2026-08-17 and cannot reach earlier posts.

Tropical Storm Lala is underway and slowly intensifying with 40-45 knot winds. The environment is not ideal with strong wind shear out of the west and dry air at the same time.

Another Eastern Pacific tropical storm formed, too —> named Hernan. It is also having trouble with wind shear, and seems to have decoupled from its convection.
